3. If you've got +5V then install a jumper at W23 - its right next to L1002 (the left inductor) in the picture above - this will bring power to the rest of the board. If you don't have +5V then something is wrong.
## Cam/crank input
The cheaper way which works for Hall sensors only is to use op-amps channels.
For rev 0.1 you can use channels 9 & 11. To enable this configuration you would need to run a yellor jumper wire from the op-amp side of W211 to JPTODO to and a white hacky wire right from op-amp chip pads XX&XX to TODO.
