ESP32-S3 Mini Development Board, Based on ESP32-S3FH4R2 Dual-Core Processor, 240MHz USC-C (soldered header) - Waveshare 25517


ESP32-S3-Zero comes with an onboard Type-C USB connector, which exposes most of the unused pins in a small form factor. It adopts ESP32-FH4R2 as a system chip (SoC) that integrates low-power WiFi and BLE5 with 4MB Flash and 2MB PSRAM. In addition, there is a hardware encryption accelerator, RNG, HMAC, and Digital Signature modules to meet the safety requirements of IoT and provide peripheral interfaces
