A GreatFET Neighbor for the 2.4 GHz wireless band.

Required KiCad dependency:

If you are using git, the preferred way to install gsg-kicad-lib is to use the submodule:

git submodule init && git submodule update

Crocus is based on the Nordic RF nRF24L01+ and was inspired by The Next Hope Badge.

A notable capability of nRF24L01+ is 2 Mbps FSK. Many 2.4 GHz wireless transceiver ICs (including the CC2400 on Ubertooth One) only support FSK up to 1 Mbps. See Promiscuity is the nRF24L01+'s Duty for an excellent trick that can be done with Crocus.

FIXME: We don't have any firmware yet, but we should implement capabilities similar to goodfet.nrf.

Alternative pins may be selected with solder jumpers.

The default I2C address is 0x27. Alternative addresses in the ranges 0x10-0x2F, 0x50-0x67, or 0x70-0x77 may be selected with solder jumpers. Refer to the Crocus schematic and to the PCA9674 data sheet for details.
