- PCB only – for those that can do the soldering and only need the PCB
- “Regular” Funky – this is the Funky sensor less the voltage step-up circuit. Useful when you will provide 2.2 – 3.6V either thru a CR2032 coin cell battery or with two AA(A) batteries
- The step-up “Funky” has the LTC3525ESC6 voltage step-up IC on board and can be powered from a single AA(A) battery. This setup provides steady 3.3V and is useful since some sensors require voltages >3V, while the Funky alone can in theory operate down to 2.2V
The current PCB I have for the Funky has the step-up inductor way too close to the RFM12B and requires a hack job to solder. I have ordered a fixed PCB and will receive it the next 14 days. If you need the “Regular” Funky only, then the current PCB is just fine. This will be the only option available in store until I receive the fixed PCBs.
