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

waveshare esp32 s3 tiny kit a mini development board

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), […]

Unexpected Maker NANOS3 A ESP32 S3 Powred Dev Board

Seon Rozenblum, better known as Unexpected Maker, has launched NANOS3  a development board that claims to be the world’s smallest, fully-featured ESP32-S3 module! This new module packs all the peripherals, and wireless connectivity features of an ESP32-S3 while being even smaller than the TinyPICO Nano. The module features two variants one with an onboard 3D antenna and the other with an u.FL connector. Previously we have written about TinyS3, FeatherS3, and ProS3 boards from Unexpected Maker we have also covered many unique ESP32-S3 boards like the ESP32-S3 PowerFeather Board with solar input, the Waveshare ESP32-S3-Relay-6CH, the ESP32-S3 4G dev boards and more feel free to check those out if you are interested in ESP32 boards with advanced features.
