ESP32 SuperMini IOT Development Board (Unsoldered / ESP32-S3)

Description

ESP32-S3 SuperMini IoT Development Board (Unsoldered) is an ultra-compact, high-performance development board built around the ESP32-S3 dual-core processor. It packs 2.4GHz Wi-Fi, Bluetooth 5.0 LE, 4MB Flash, and 2MB PSRAM into a thumb-sized form factor, making it well suited for embedded IoT, wearable electronics, smart sensors, and compact wireless control applications. This unsoldered version ships without header pins, giving you full flexibility to solder your own connectors or wires directly for a low-profile build. It includes USB-C for programming and charging, along with an onboard Li-ion/LiPo battery charging circuit (B+/B- pads) for battery-powered projects.
