ESP32-S3-Matrix board features 64 LEDs, GPIO pins, 9-axis “attitude” sensor for robotics and motion control applications

The Waveshare ESP32-S3-Matrix is a microcontroller development board designed for AIoT applications, featuring a larger 8×8 RGB LED matrix (64 LEDs) compared to the 5×5 RGB LED matrix (25 LEDs) on the ESP32-C3/ESP32 based “C3FH4 RGB” / “PICO D4 RGB” board. In addition to that the Waveshare board features two 10-headers for GPIOs, UART, and power signals, along with an integrated QMI8658C attitude sensor (9-axis IMU sensor), making it ideal for robotics and motion control projects. Recently we have seen Waveshare introduce affordable products that are perfect for embedded development like the $15 1.69-inch IPS touch LCD module, the $6.99 ESP32-C6-Pico Board, the $4.99 ESP32-S3-Tiny board and much more feel free to check those out if you are interested in those. Waveshare ESP32-S3-Matrix dev board specifications: MCU – Espressif Systems ESP32-S3FH4R2 CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration Memory – 512KB RAM, […]

$4.99 ESP32-S3-Tiny board measures just 23.50 x 18 mm

Waveshare has recently released the ESP32-S3-Tiny mini development board powered by ESP32-S3 wireless MCU and measuring just 23.50 x 18 mm. Due to its compact form factor, it does not include a USB-to-UART converter or a USB port. That is why, you will need an additional adapter board with an FPC cable to program it, which costs only $1. Despite its small size, the board is feature-rich. It includes 34 multi-function GPIO pins, along with Wi-Fi, BLE, SPI, I2C, UART, ADC, PWM, and more. The design of the board is very similar to the Raspberry Pi RP2040-powered Waveshare RP2040-Tiny board that we covered last year. However, what sets this board apart is its 34 I/O pins, compared to the 23 found on the RP2040-Tiny board, and wireless connectivity. We’ve also written about several other boards with compact form factors, such as the Unexpected Maker NANOS3 board (28 x 11 mm), […]

FOCn ESP32-S3-based, medium-power BLDC driver module supports SimpleFOC

European engineer, Matej Planinšek of PLab, has developed the FOCn — a medium-power BLDC driver module based on ESP32-S3 WiSoC capable of delivering up to 10A of continuous current. It is compatible with the SimpleFOC Arduino library making it easier to control BLDC (brushless direct current) and stepper motors with the field-oriented control algorithm. The developer was inspired to create the FOCn module when their search for a custom-made, SimpleFOC-compatible driver module that met all their requirements failed. The name is related to field-oriented control (FOC) and also means “face slap” in Slovenian, Matej’s native language. The driver module is based on the ESP32-S3 dual-core XTensa LX7 microcontroller which provides Wi-Fi and Bluetooth connectivity. The microcontroller further supports ESP-NOW, a low-power and low-latency communication protocol, which makes it possible for multiple FOCn boards to talk to one another. FOCn driver module specifications: MCU – ESP32-S3 dual-core XTensa LX7 microcontroller @ […]
