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 and tell us which board(s) we should add next!
ESP32 General Features:
Specific Peripherals made available on smôl ESP32:
Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.
Skill Level: Competent - You might need to break out the power tools. Nothing beyond a power drill or rotary tool should be required, but you might have a hard time with just a screwdriver and hammer. Cutting holes into plastic or metal might be required.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.
