The OKD Acorn ESP32 Dev Board is a packed ESP32 development board with 8MB of Flash and a whopping 26 GPIO! 76.6 mm* 45 mm Sized Board (Slightly smaller than a credit card), this is our largest board we offer!

2x18P pinout layout, standard 2.54mm pitch (100mil) and breadboard friendly, with one side dedicated for peripheral (power, programming, communication) and the other side for GPIO

ESP32-WROOM-32E, comes with latest ECO V3 Dual Core 32-bit LX6 microprocessor with clock up to 240MHz, ULP co-processor, 520kB SRAM, 8MB Flash.

802.11b/g/n WiFi Connectivity, support multi modes STA/AP/STA+AP mode

Bluetooth 4.2 Connectivity, supports classic BT and Low Energy (LE) protocol.

CH340C UART to USB Bridge, full-speed programmer and data port

XC6220 LDO, providing +3.3V power up to 1 amp with green operation mode which automatically switches to power save mode with a light load

Built-in LED/RGB, single color active-low LED connected to pin GPIO2, and SK6812 addressable RGB LED connected to pin GPIO4. SK6812 data out is exposed also, so you can create a chain of RGBs easily!

MicroSD Connector, connected via SPI with slave select (SS) at pin GPIO5 full or high speed (Recommend the SDFat Library).

USB Type-C Connector, no more frustration when connecting a USB cable, plug it in any direction you want
