Neighbors
already designed
Begonia: a GIMME for GreatFET
Crocus: nRF24L01+
Daffodil: through-hole prototyping
Scorzonera: interface for FLIR PM-series thermal cameras (AM7969 & RS232)
Spot: a chonky indicator LED
some progress made
Canna: basic 2-channel CAN neighbor
Edelweiss: CC1310 (depending on progress, could consider newer cc1352 that supports more)
Foxglove: advanced level shifting and probing (support for +/- 12v would be awesome…)
Gladiolus: IR
Heliopsis: googly eyes
Hydrangea: NFC
Indigo: ChipWhisperer 20-Pin Connector + Voltage Glitching
Jasmine: Lithium Polymer battery pack/charger
Kniphofia: iCE40 FPGA capable of remapping neighbor pins
Lily: RF power detector
Lucky Bamboo: quadruple 2.4 GHz ADF7242 transceiver for monitoring Bluetooth LE advertising channels
Magnolia: TDR, dual ethernet (LAN tap)
Narcissus: a jig for testing GreatFET One
Orchid: Breakout board for common hardware hacking interfaces
Peony: SDR based on AT86RF215IQ
Quince: 2.4 GHz SDR using 1 bit ADC over SGPIO
Rhododendron: Hi-Speed USB passive sniffer
Stellaria: experimental random number generator
Tulip: an awesome blinky neighbor
Ursinia: Grove base
rough ideas
RNG
DAQ
pulse generation (TTL)
arbitrary waveform generation
magstripe
barcode
dual cc1101
cc1200 + cc2500 for rfcat-like functionality in Sub-GHz and 2.5 GHz
cc1352 for WiFi, BLE 5, Zigbee, Thread, Wireless M-Bus, 802.15.4g, 6LoWPAN, KNX RF, Wi-SUN®, and 2FSK/4FSK proprietary protocols
