Last year, Olimex launched their first FPGA board with iCE40HX1K-EVB. The board is very cheap at 22 Euros, but what you can do with it is limited since it only comes with 1280 logic cells. The company has now introduced an upgraded model called iCE40HX8K-EVB with 7680 logic cells, and more I/O headers. Olimex iCE40HX8K-EVB specifications: FPGA – Lattice Semi iCE40HX8K-CT256 FPGA with 7680 logic gates, 960 Logic Array Blocks, and 128 Kbit memory System Memory – 256Kx16 SRAM (512KB SRAM) Storage – 2MB serial flash Expansion 34-pin connector to access FPGA I/Os 4x 40 pin connectors for GPIOs Debugging / Programming – 10-pin “PGM” connector Misc – 2x user buttons, reset button, 2x user LEDs, power & programming status LEDs Power Supply – 5V via power jack Dimensions – 67×65 cm The board is open source hardware with the KiCAD schematics and PCB layout, BoM, and Gerber files available […]
Olimex Launches 22 Euros ESP32-GATEWAY Board with Ethernet, WiFi and Bluetooth LE
Olimex has just launched ESP32-GATEWAY board, as cost-down version of their ESP32-EVB board, still with Ethernet, WiFi, and Bleutooth LE, but without any relays, CAN bus, nor IR control, less I/Os, and a smaller footprint. Olimex ESP32-GATEWAY specifications: Wireless Module – ESP32-WROOM32 module with 802.11 b/g/n WiFi and Bluetooth LE Wired Connectivity – 10/100M Ethernet with RJ45 jack (via LAN8710A) External Storage – micro SD slot Expansion – 20-pin GPIO connector USB – 1x micro USB port for debugging (CH340T) and power Misc – Reset and user buttons Power Supply – 5V via micro USB port Dimensions – 62 x 50 mm Another change is the lack of a LiPo charger to run the board from batteries. Just like most Olimex boards, ESP32-GATEWAY is open source hardware with KiCAD design files available on Github. The software directory is still empty, but Ethernet demo code using ESP32-IDF has been pushed for […]
A64-OLinuXino Open Source Hardware Allwinner A64 Development Board Launched for 50 Euros
Several boards based on Allwinner A64 quad core 64-bit ARM processor have been available on the market for a while, with products such as Pine A64(+), NanoPi A64, or Banana Pi BPI-M64. Olimex also has been working on A64-OLinuXino since late 2015, and the company has now formally launched the board for 50 Euros, which also happens to be the very first open source hardware board based on Allwinner A64. A64-OLinuXino Rev. C board specifications: SoC – Allwinner A64 quad core Cortex-A53 processor with Mali-400MP2 GPU System Memory – 1 or 2GB DDR3L @ 672 MHz Storage – micro SD slot, Optional 4 or 16GB industrial grade eMMC flash, optional SPI Flash Video Output & Display I/F – HDMI, 20-pin MIPI & 40-pin LCD display connectors Audio – Via HDMI, 3.5mm Audio In and Out jacks (Headphone output and microphone input can be changed to Line-in and Line-out via jumpers) […]
Olimex ESP32-EVB Board with Ethernet, CAN Bus, and Relays up for Sale for 26 Euros
One of the new feature of Espressif ESP32 SoC over ESP8266 is the inclusion of an Ethernet MAC interface, but so far few boards come with an RJ45 jacks. ESP32 Monster board is an option, also including an OLED Display and CAN Bus, and sold on Tindie for $35, but Olimex has now stocked their ESP32-EVB board with Ethernet, CAN Bus, and two relays, and you can purchase it for 26 Euros per unit, and less in larger quantities. Olimex ESP32-EVB Rev. B specifications: Wireless Module – ESP32-WROOM32 module with 802.11 b/g/n WiFi and Bluetooth LE Wired Connectivity – 10/100M Ethernet with RJ45 jack (via LAN8710A) External Storage – micro SD slot Relays – 2x 10A/250VAC relays with LED status Expansion 40-pin GPIO female header (2.54mm pitch) UEXT connector for sensors and modules CAN Bus USB – 1x micro USB port for debugging (CH340T) and power Misc – Reset and […]
22€ Olimex ESP32-EVB ESP32 Development Board Features an Ethernet Port and Relays
We already have a good choice of ESP32 development boards, but none of the ones I’ve seen make use of the Ethernet MAC interface found in Espressif ESP32 SoC. Olimex has changed that with their ESP32-EVB featuring ESP32-WROOM32 module as well as one Fast Ethernet port and two relays. Olimex ESP32-EVB specifications: Wireless Module – ESP32-WROOM32 module with 802.11 b/g/n WiFi and Bluetooth LE Wired Connectivity – 10/100M Ethernet RJ45 port External Storage – micro SD slot Relays – 2x 10A/250VAC relays Expansion 40-pin GPIO female header (2.54mm pitch) UEXT connector for sensors and modules Misc – 2x user buttons Power Supply 5V power jack LiPo charger and step up converter allowing ESP32-EVB to run from LiPo battery The company still have to write software samples, and do some testing to make sure the board work before going into mass production. Once everything is cleared, the board will be sold […]
ESP32-WROVER-KIT Devkit Supports Espressif ESP32 Modules, Includes a 3.2″ LCD Display
Yesterday Olimex wrote a blog post informing us that ESP32-CoreBoard was back in stock, one the many ESP32 boards launched late this year, but still hard to get. The company also mentioned they’d have limited quantity of the new ESP32-WROVER with JTAG and LCD display together with the picture below. ESP32 is quite more powerful than ESP8266 so it makes sense to have an ESP32 development kit with an LCD display. A quick DuckDuckGo search led me to ESP-WROVER-KIT Getting Started Guide, where we can find more details including the overall specifications: Compatible with ESP-WROOM-32 and ESP32-WROVER modules based on ESP32 dual core Tensilica L108 processor clocked at up to 240 MHz with WiFi and Bluetooth LE connectivity Storage – Micro SD slot Display – 3.2″ LCD display connected via SPI USB – 1x micro USB port Expansion 8-pin UART header 6-pin SPI header 48-pin header for I/Os and camera […]
Linux 4.9 Release – Main Changes, ARM and MIPS Architectures
Linus Torvalds released Linux 4.9 on Sunday: So Linux 4.9 is out, and the merge window for 4.10 is thus open. With the extra week for 4.9, the timing for the merge window is obviously a bit awkward, and it technically closes in two weeks on Christmas Day. But that is a pure technicality, because I will certainly stop pulling on the 23rd at the latest, and if I get roped into Xmas food prep, even that date might be questionable. I could extend the merge window rather than cut it short, but I’m not going to. I suspect we all want a nice calm winter break, so if your stuff isn’t ready to be merged early, the solution is to just not merge it yet at all, and wait for 4.11. Just so you all know (I already bcc’d the main merge window suspects in a separate mailing last […]
ESP32 Updates – ESP32-S Module Replaces ESP3212, ESP32 DevBoards for Sale, Arduino & NodeMCU Support
There have been some developments with regards to Espressif ESP32 in the last month since my post about upcoming ESP32 development boards. First ESP3212 module is no more, and has been replaced with ESP32-S module with about the same features, but it’s not pin-to-pin compatible, so the new module won’t work with older breakout boards made for ESP3212. ESP32-S is now out of stock on Seeed Studio, but you’ll find it on IC Station, Banggood, and others shops. One good news is that it’s now easier to buy – or at least pre-order – ESP32 development boards, although stock may still be an issue, as the platform is very popular. If you live in the US, you can now backorder “Sparkfun ESP32 Thing” for $19.95. ESP32 board can be powered by either a micro USB power supply or a LiPo battery, and exposes close to 30 I/O pins. ESP32 developer […]
