Radiona ULX3S Open Source Hardware ECP5 FPGA Development Board Launched for $99 and Up (Crowdfunding)

ULX3S Lattice ECP5 FPGA Educational Board

Last summer, we wrote about Radiona ULX3S education board combining a Lattice Semi ECP5 FPGA with an Espressif Systems ESP32 WiFi & Bluetooth WiSoC. Designed for a digital logic course at the University of Zagreb, the board is open-source hardware with KiCAD hardware design files released on GitHub, and programmable with the Arduino IDE (FPGArduino) and ProjectTrellis open-source toolchain. At the time, there was only a version based on Lattice ECP5 85F with 84K LUT, but they’ve now made versions with cheaper variants of ECP5 FPGA and launched the board on Crowd Supply. Radiona ULX3S specifications: FPGA (one of the other) Lattice ECP5 LFE5U-85F-6BG381C with 84K LUT Lattice ECP5 LFE5U-45F-6BG381C with 44K LUT Lattice ECP5 LFE5U-12F-6BG381C with 12K LUT System Memory – 32MB SDRAM @ 166 MHz Storage – 4–16MB Quad-SPI Flash for FPGA config and user data storage; MicroSD slot Audio – 3.5 mm jack with 4 contacts (analog […]

Wio Terminal Features Microchip SAMD51 MCU, Dual-Band WiFI & Bluetooth WiFI, and 2.4″ LCD

Microchip SAM D5x Arm Cortex-M4 microcontrollers were introduced in 2017, and the next year we started to see Arduino or MicroPython compatible board brought to market including Adafruit Metro M4 or Tachyon boards. Seeed Studio has now introduced its own Arduino & MicroPython compatible SAMD51 platform with Wio Terminal also integrating an RTL8720DN dual-band WiFi 4 and Bluetooth 5.0 chip, and 2.4″ LCD display. There are also Grove connectors to add sensor modules, and a 40-pin header to use the device like a Raspberry Pi HAT. Wio Terminal features and specifications: MCU – Microchip SAMD51 (ATSAMD51P19) Arm Cortex-M4F microcontroller @ 120 MHz (can be overclocked to 200 MHz) with 192KB RAM, 512KB flash Storage – 4MB external SPI flash, MicroSD card slot up to 16GB Display – 2.4″ LCD screen with 320×240 resolution (ILI9341 driver) Audio – Microphone and buzzer Connectivity – Dual-band WiFi 4 802.11b/g/n and Bluetooth 5.0 via […]

2.5-inch Pico-ITX SBC Offers LVDS, HDMI & DisplayPort Video Interfaces, Dual Gigabit Ethernet

Today I learned that Pico-ITX boards were also called 2.5-inch boards since they are about the size of a 2.5-inch SATA drive. Kontron pITX-APL V2.0 is one such 2.5-inch Pico-ITX SBC powered by an Intel Atom E39XX or Celeron Apollo Lake processor. The board can drive three independent displays via its 24-bit LVDS interface, HDMI and mini DisplayPort 1.2 output, comes with two Gigabit Ethernet ports and support for 4G LTE connectivity via M.2 slot and SIM card socket. Those features make it suitable for a wide range of applications including industrial client applications, kiosk, infotainment, digital signage, and POS systems. Kontron pITX-APL V2.0 specifications: Apollo Lake SoC variants Intel Atom x7-E3950 quad-core processor @ up to 2.0 GHz with 18EU Intel HD graphics; 12W TDP Intel Atom x5-E3940 quad-core processor @ up to 1.8 GHz with 12EU Intel HD graphics; 9.5W TDP Intel Atom x5-E3930 dual-core processor @ up […]

K1 Smart Lock Box Secures Door Keys with Fingerprint, Mobile App, or Passcode (Crowdfunding)

We’ve previously reported about smart dock look solutions such as Xiaomi Sherlock M1 which allows you to provide access control without keys using your smartphone instead. Security concerns aside, one disadvantage of the Xiaomi smart lock is that it is only compatible with some doors, and can be complicated to install. YEEUU TECH has found a way that works with all doors with K1 smart lock box, a simple rugged box used to store physical keys, and that can be opened with a smartphone app, fingerprints, or a passcode. K1 smart lock box features and specifications: Bluetooth connectivity Permanent or temporary passcode unlock via backlit keypad; up to 100 passwords Permanent or temporary fingerprint unlock (optional); up to 50 fingerprints Remote control and instant share Time window support In-app management, access logs USB – 1x USB Type-C port for emergency power to open the box when batteries are dead Security […]

FriendlyELEC SOM-RK3399V2 CPU Module Gets 4GB LPDDR4 RAM Upgrade

Last year, FriendlyELEC launched SOM-RK3399 system-on-module (SoM) powered by Rockchip RK3399 hexa-core processor combined with 2GB DDR3 memory, 16to 64GB flash, and a built-in WiFi 5 module. Contrary to most SoM’s on the market, SOM-RK3399 could work in standalone mode thanks to two USB-C ports, although it could also be integrated into a carrier board to create a complete development board with more ports and interfaces. The company has now introduced an update with SOM-RK3399V2 CPU module with 4GB LPDDR4 RAM, as well as a small change in the layout for the LED’s and buttons, but the rest of the features remain the same. The company also appears to have changed the way they handle cooling with SOM-RK3399V2 shipping with a heatsink, while SOM-RK3399 cooling was handled by a heatsink + cooling connected to the carrier board. SOM-RK3399V2 specifications: SoC – Rockchip RK3399 big.LITTLE hexa-core processor with 2x Cortex-A72 cores […]

AMD Ryzen Embedded based SBC-VR1000 SBC to Power Edge Computing & Graphics Applications

We just wrote about a 3.5″ Ryzen Embedded SBC a few days ago, namely SECO SBC-C90 single board computer, after mentioning there were few such AMD options in the 3.5-inch form factor with the only other board we covered so far being IBase IB918. But there’s now at least a third option with Kontron introducing SBC-VR1000 3.5-inch board powered by AMD Ryzen Embedded V1000-series or R1000-series processor, and designed for “intensive edge computing and graphics applications” including digital signage, digital casino gaming, kiosk, retail, banking, education, medical imaging, as well as industrial control and automation. Kontron SBC-VR1000 specifications: SoC (one or the other) AMD Ryzen V1605B quad-core processor @ up to 3.60 GHz with 4M cache, AMD Radeon Vega 8 GPU; 15 W TDP AMD Ryzen V1202B dual-core processor @ up to 3.20 GHz with 4MB cache, AMD Radeon Vega 3 GPU; 15 W TDP AMD Ryzen R1606G dual-core processor […]

$5 Sinilink WiFI USB Power Switch Works with Tasmota Firmware, Supports up to 20V/5A

Late last year, ITEAD launched Sonoff Micro WiFi USB switch that allows you to turn on and off USB powered devices over WiFi using eWelink app for Android or iOS. It integrates with Amazon Alexas and Google Home, and does the job, but people who like to use the open-source Tasmota firmware will be disappointed to learn it’s not based on ESP8266 processor hence not compatible. Luckily, there’s another option: Sinilink WiFi USB switch (aka XY-WFUSB) based on ESP8266 WiFi SoC, and supporting up to 20V/5A according to the manufacturer. It is currently sold for under $5 including shipping on Aliexpress. Sinilink XY-WFUSB specifications: WiSoC – Espressif ESP8266 processor with 802.11b/g/n WiFi 4 USB Input – USB type-A female port supporting 3.5V to 20V up to 5A (100 Watts max) USB Output – USB type-A male port up to 100W Misc On/off button – Pressing 5 seconds also change the […]

Meshtastic Mesh Networking Project Combines ESP32, LoRa and GPS Radio

Meshtastic is a project using off-the-shelf, inexpensive ESP32-based hardware with GPS & LoRa connectivity to create mesh networks helping hikers. skiers, paragliders, or people exercising other outdoor activities communicate short messages such as their GPS location. This allows each member of a private mesh network to see the location and distance of all other members and read/or any text messages sent to a group chat. No phone is required unless you have an ESP32 LoRa board without GPS in which case it would get the GPS coordinates from your phone over Bluetooth. A phone is also needed to send a message. The project currently works on three different boards TTGO T-Beam, TTGO LORA32 and Heltec LoRa 32. The T-Beam is recommended as it sells for around $26 plus shipping and features a 18650 battery holder so you can source the battery easily locally. Just make sure to purchase the right […]
