Using SenseCraft firmware for no-code programming on Wio Terminal

In the conclusion of our SenseCAP K1100 Sensor Prototype kit review with LoRaWAN and Vision AI, the author suggested that it would be great if SeeedStudio could develop a new firmware that can connect without coding instead of using Arduino programming: I had to rely on my knowledge and experience with LoRaWAN to transmit data wirelessly over long distances. That’s because LoRaWAN has a more complicated connection process than Wi-Fi or Bluetooth. It would be great if Seeed Studio could develop a new firmware that can connect without any coding It did not take long, as SeeedStudio very recently released the first version of SenseCraft open source smart sensor software for no-code sense, process, and uplink that happens to be compatible with the Wio Terminal part of the SenseCAP K1100 development kit. So let’s test the new SenseCraft firmware together. SenseCraft navigation keys We can use Wio Terminal’s joystick as follows: […]

ESP32 DevKitC V4 IoT development board ships with ESP32-WROOM-DA dual antenna module

The ESP32 DevKitC V4 is now selling with the ESP32-WROOM-DA module with two PCB antennas that was introduced last year in order to offer a longer WiFi range and better reliability. The development kit is exactly the same as the other ESP32 DevKitC V4 models, and the only difference is the dual antenna design. When running a recent version of the Arduino Core for the ESP32 (2.0.3 or greater), the ESP32 will automatically switch to the antenna with the strongest signal in order to deliver the best connectivity possible. ESP32 DevKitC V4 specifications: Wireless module – ESP32-WROOM-DA (PDF datasheet) with SoC – Espressif Systems ESP32-D0WD-V3 dual-core LX6 microprocessor with 520 KB SRAM, 2.4 GHz WiFi 4 and Bluetooth 4.1 connectivity Storage – 4MB SPI flash Two PCB antennas (ANT1 and ANT2) USB – 1x Micro USB port for power, programming, and debugging through USB-to-UART bridge up to 3 Mbps Expansion […]

ELLO LC1 – A 2mm thin DIY “computer” based on Microchip PIC18 8-bit MCU

We often write about business card or credit card-sized boards, but it’s only true for 2D dimensions, as most boards are over a centimeter thick, with possibly the thinnest we’ve covered being the Khadas Edge2 SBC that’s just 7mm thick. So Kn/vD took it upon himself to build a DIY computer that was really about the size of a credit card, and came up with the ELLO LC1 based on a Microchip PIC18 8-bit microcontroller, featuring an integrated display and keyboard, and powered by a coin-cell battery. It’s just 2mm thin. ELLO LC1 specifications: MCU – Microchip PIC18 (PIC18F47Q83-I/PT) 8-bit microcontroller with 13KB RAM and 128KB flash, out of which 64KB are reserved as user file storage Display – 20×4 character text panel (Display Visions EADOGM204N) Keyboard – 48x touch panels on the PCB Expansion – 12-pin unpopulated header for debugging (ICSP) and GPIO expansion Misc – Power button Power […]

Raspberry Pi RP2040 gets into BBC Micro:bit lookalike board

ELECFREAKS Pico:ed V2 is a Raspberry Pi RP2040 board heavily inspired by the BBC Micro:bit with an edge connector exposing rings suitable for crocodile clips, a 17×7 LED matrix display, and designed for the classroom. We’ve seen several BBC Micro:bit clones – or rather adaptations – over the years with boards such as the SiFive Learn Inventor, Elecrow Mbits, and HiHope “Big Brother” board. The Pico:ed V2 adds to the list, and the main differences are that it is based on the Raspberry Pi RP2040 microcontroller instead, and does not come with wireless connectivity relying on a USB interface only. ELECFREAKS Pico:ed V2 specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133Mhz with 264kB of SRAM Storage – 2MB QSPI flash Display – 17×7 dot-matrix display USB – 1x micro USB 1.1 port for power, data, and programming I/Os 25-pin notched “Wavy” connector with up to […]
