AI-Thinker introduces 5 ESP32-C3 modules pin compatible with ESP8266 & ESP32 modules

ESP32-C3 is the first RISC-V wireless SoC from Espressif Systems, and at the time of the initial announcement promised to cost about the same as ESP8266 but adds support for Bluetooth 5.0 LE besides 2.4 GHz WiFi, and retain software compatibility through the ESP-IDF framework. We were also told the goal was to provide ESP8266 compatible modules, and AI-Thinker has just announced five new ESP32-C3 modules compatible with earlier ESP8266 & ESP32 modules as shown in the table below. The table above is quite low resolution but that’s the best I could obtain from the company… It’s also a complete mess, not showing all alternative ESP8266 or mistaken in board sizes. So I’ll try to give a short summary of differentiating features and equivalent ESP8266/ESP32 modules: ESP32-C3F is meant to replace ESP-12F with a 24 x 16 mm form factor. It does add an IPEX connector, besides the PCB antenna. […]

Board::mini development tools offer a complete Vehicle-Hacking Platform (Crowdfunding)

board::mini base CAN bus automotive development board

If you are looking to connect to a vehicle’s CAN bus, then the newly launched open-source board::mini development tools include a board and expansion boards that will aid your application. BMC labs have introduced a development board based on the STM32 MCU and supporting expansion boards to increase the capabilities of the baseboard via a crowdfunding project. As mentioned earlier, the board:mini base development board features an STM32 MCU at its heart and comes with a CAN transceiver. For those who do not know what a CAN transceiver is, it just transmits and detects data on the CAN bus. The board:mini project also includes three expansion boards designed to fit on top of the base development board. The bmc::board project was born to produce development tools appropriate for both field- and industrial-prototyping work. These boards were not designed to sit on a workbench. We ourselves have a habit of strapping […]
