ESP32-S3 Mini Development Board N8R8 - 8MB Flash 8MB PSRAM - 2.4GHz WiFi & Bluetooth - Unsoldered

The Waveshare ESP32-S3-Zero N8R8 is a tiny ESP32-S3 development board with 2.4GHz Wi-Fi and Bluetooth 5 (LE), packing a dual-core 240MHz processor, 8MB Flash and 8MB PSRAM, USB-C and an onboard RGB LED into a thumbnail-sized footprint. This version comes with pin headers unsoldered, so you can solder it straight onto a carrier board or fit headers yourself. The extra memory makes it the better choice for LVGL displays, camera and audio projects, large web servers and other memory-hungry applications. Its castellated edges let it be soldered directly onto a PCB like a module, making it ideal for compact IoT devices, wearables, smart home sensors and embedded projects. It can be programmed with Arduino, ESP-IDF or MicroPython.
