ESP32 dual-mode WIFI+Bluetooth development board

Description:

Descriptive
- It can operate independently as a minimal and independent system
- The ESP integrates WiFi, traditional Bluetooth and BLE beacons, with two high-performance 32-bit LX6 processors, 7-stage pipeline architecture, main frequency adjustment range from 80 MHz to 240 MHz, integrated sensor, Hall effect sensor, temperature sensor, ...
- Ultra-compact 802.11b/g/n Wi-Fi + BT/BLE SoC module; Low-power 32-bit dual-core CPU for application processors; Up to 240 MHz, up to 600 DMIPS; 520 KB integrated SRAM, 4 M external PSRAM
- Fully compatible with WiFi 802.11b/g/n/e/i and Bluetooth 4.2 standards, it can be used as a master mode to create an independent network controller or as a slave for other host MCUs.
