smôl ESP32

Our RedBoards are great. But don\'t they sometimes seem a little **_BIG_**?!

Enter **smôl**, a new range of boards which are both small in size and small on current draw. It\'s a smôl world!

The smôl ESP32 Processor Board combines Espressif\'s ESP32 (ESP32-D0WDQ6-V3) with our smôl FPC interconnect to bring a processor board with reliable wireless capabilities into our smôl ecosystem.

The ESP32 includes a laundry list of functionality, including the dual-core Tensilica LX6 microprocessor, 240MHz clock frequency, 520kB internal SRAM, integrated WiFi transceiver and hardware accelerated encryption (AES, SHA2, ECC, RSA-4096). With this smôl processor board, you have access to both SPI and I2C interfaces plus 2 general use IO pins. We\'ve added a miniature WS2812C RGB LED for visual feedback and of course it comes with USB-C connectivity as standard. Add to that 16MByte (128Mbit) of flash storage and sleep current of around 500µA, and you\'ve got a perfect storm of miniature versatility. Need to get that sleep current even lower? Pair the smôl ESP32 with one of our intelligent Power Boards and you can drop the sleep current below 10µA!

_**smôl** is an ecosystem of miniature processor boards, peripheral boards, power boards and accessories. Designed to be both physically small and to have the smallest possible current draw, smôl is the perfect choice for applications like wildlife tracking or discrete long-term monitoring. smôl boards are designed to stack one on top of the other, using 16-way 0.5mm-pitch Flexible Printed Circuits (FPCs) to provide the interconnect from one board to the next. Looking for a really compact solution for your next project? This is it!_

_We will be adding new smôl boards over the coming months. Don\'t see the board you need for your application? Reach out to us via the [SparkX Forum](https://forum.sparkfun.com/viewforum.php?f=123) and tell us which board(s) we should add next!_
