Programming RejsaCAN-ESP32-S3 CAN bus board with Arduino for car “hacking”

The RejsaCAN-ESP32-S3 is an ESP32-S3 board suitable for developers who want to build a car-related project. It can control or read the data from the OBD-II connector in your car using 2.4 GHz Wi-Fi or/and Bluetooth 5 (LE), or for IoT projects, connecting a sensor to the board and sending data to an app, the cloud, or log the data to a microSD Card. The board is designed to be small enough to be installed in a car. The board is an evolution of the previous ESP32-based RejsaCAN-ESP32 with the developer – Magnus Thomé – switching to the ESP32-S3 chip as previously announced. The main specifications are similar, but the ESP32-S3 is a newer LX7 processor with Bluetooth LE 5.0 support, and the ESP32 board had to use a USB-to-serial chip to communicate or upload the program through a PC, but the new board uses the USB interface on […]

Lolin S3 Mini – Tiny $5 ESP32-S3 board follows Wemos D1 Mini form factor

LOLIN S3 Mini is a tiny ESP32-S3 WiFi and Bluetooth IoT development board that follows the Wemos D1 Mini form factor and supports its equally tiny stackable shields to add relays, displays, sensors, and so on. Wemos/LOLIN introduced their first ESP32-S3 board last year with the LOLIN S3 board with plenty of I/Os and an affordable $7 price tag. But I prefer the company’s Mini form factor because of its size and the ability to select add-on boards to easily add a range of features to your projects. So I’m pleased to find out the company has now launched the LOLIN S3 Mini following the ESP32-C3 powered LOLIN C3 Mini board unveiled in March 2022. LOLIN S3 Mini specifications: WiSoC – Espressif Systems ESP32-S3FH4R2 CPU – dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration Memory – 512KB RAM, 2MB PSRAM Storage – 4MB QSPI […]
