SKU:K122
Stamp-C3U Mate is an accessory kit for the Stamp-C3U minimum core board.
The kit includes a Stamp-C3U along with female headers, male headers, a HY2.0-4P female socket and other practical accessories, making it easy to integrate the Stamp-C3U into your circuit quickly.
Stamp-C3U is a cost-effective RISC-V minimum core board powered by the ESP32-C3 SoC, which integrates a 32-bit single-core RISC-V processor running at up to 160 MHz. It comes with 400 KB SRAM + 4 MB Flash and built-in 2.4 GHz Wi-Fi. The module supports secure boot, flash encryption and digital signature. Despite its small size, it offers powerful features to meet a wide range of IoT application requirements.
