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 Environmental Peripheral Board brings three versatile, low-power sensors to your smôl ecosystem:
  • BME280 - Pressure, Humidity and Temperature sensor
  • SGP40 - VOC Air Quality sensor
  • VEML7700 - Ambient Light (Lux) sensor
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!
Experimental Product: SparkX products are rapidly produced to bring you the most cutting edge technology as it becomes available. These products are tested but come with no guarantees. Live technical support is not available for SparkX products. Head on over to our forum for support or to ask a question.
