* LED driver
* IKEA TRÅDFRI module

The tiny IKEA TRÅDFRI module is used in many of their products, and is actually a small piece of circuit board with pins exposed. This board uses the energy-efficient Silicon Labs [EFR32MG1P132F256GM32](https://www.silabs.com/products/wireless/mesh-networking/efr32mg-mighty-gecko-zigbee-thread-soc/device.efr32mg1p132f256gm32) microcontroller (MCU), which is a ARM Cortex M4 with 256 KiB of flash and 32 KiB of memory.
The tiny IKEA TRÅDFRI module is used in many of their products, and is actually a small piece of circuit board with pins exposed called ICC-1. This board uses the energy-efficient Silicon Labs [EFR32MG1P132F256GM32](https://www.silabs.com/products/wireless/mesh-networking/efr32mg-mighty-gecko-zigbee-thread-soc/device.efr32mg1p132f256gm32) microcontroller (MCU), which is a ARM Cortex M4 with 256 KiB of flash and 32 KiB of memory.

Power requirements for the ICC-1 module:
ICC-1 can be supplied from a regulated power supply down to 1.85V in all conditions.
During peak load transients, power supply can be up to 145mA when using high power
mode.

For more information see the [FCC Registration](https://fccid.io/FHO-ICC-1/) with documents.



You can take out the board, and hook it up to your own lighting solutions. Or, you can flash it with your [own firmware](#custom-firmware), for other purposes.
