Original 8 x AA battery holder with 5.5mm/2.85mm Plug and On/Off Switch – PartsCountry

Description

This is a compact WiFi development board from Waveshare based on the ESP32-S2 with a pinout that supports most HATs designed for the Raspberry Pi Pico!

The board offers numerous peripheral interfaces, integrated low-power Wi-Fi System-on-Chip (SoC), USB-C connectivity and mass memory. Equipped with a hardware crypto accelerator, RNG, HMAC and Digital Signature module, it can meet the security requirements of the Internet of Things.

Multiple low-power operating states are available to satisfy power requirements in IoT, mobile devices, wearable electronics, smart home and other application scenarios.

We also stock a version with a 0.96″ LCD!
