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 […]

$60 M5Stack CoreS3 ESP32-S3 IoT controller comes with 2-inch display, VGA camera, multiple sensors

M5Stack CoreS3 is a battery-powered ESP32-S3 IoT controller with WiFi and Bluetooth connectivity, a 2-inch touchscreen display, a 0.3MP camera, a microSD card slot for storage, several sensors, plenty of I/Os, a USB Type-C OTG port, as well as a 9V to 24V DC input port. That’s the second ESP32-S3 IoT controller from M5Stack we’ve seen this year, as the CoreS3 follows the smaller M5Stack AtomS3 with a 0.85-inch display, only a few I/Os, and fewer features overall although it does come with an IR transmitter that’s missing from the larger CoreS3. M5Stack CoreS3 specifications: Wireless MCU – Espressif Systems ESP32-S3FN16R8 dual-core 32-bit Xtensa LX7 microcontroller with AI vector instructions up to 240MHz, RISC-V ULP co-processor, 512KB SRAM, 2.4GHz WiFi 4 (802.11b/g/n), Bluetooth 5.0 BLE + Mesh, 16MB flash, 8MB PSRAM Antenna – Internal “3D” antenna Storage – MicroSD card slot Display – 2-inch display with 320×240 resolution via ILI9342C […]

HealthyPi 5 WiFi & BLE biosignal-acquisition sensor platform captures body temperature, ECG, PPG, SpO₂, and other vitals (Crowdfunding)

HealthyPi 5 is an open-source sensor platform for biosignal acquisition based on Raspberry Pi RP2040 microcontroller and ESP32-C3 WiFi & BLE module used to capture vitals such as electrocardiogram (ECG), respiration, photoplethysmography (PPG), oxygen saturation (SpO₂), and body-temperature data. It is a complete redesign of the HealthyPi v4 Raspberry Pi HAT with many of the same features. While the HealthyPi 5 also follows the Raspberry Pi HAT form factor and can be connected to a Raspberry Pi SBC to analyze the data, it can also be used as a standalone device with the processing handled by the RP2040 dual-core Cortex-M0+ microcontroller and connectivity through an ESP32-C3 wireless module, and data visualized on a 3.5-inch SPI display or a smartphone over WiFi or Bluetooth. HealthyPi 5 specifications: MCU – Raspberry Pi RP2040 dual-core Arm Cortex-M0+ microcontroller @ 133 MHz with 264 KB SRAM Wireless Module – ESP32-C3 RISC-V module with 2.4 […]
