Hello JMW,
Looks like the main branch of the repo still had an earlier revision of the board.
The latest version was here, on the beta branch, including C11.
I just pushed an even newer board design that we recently validated to the main branch, so this shouldn't be an issue in the future.
For most applications, it's not actually a problem to leave out C11; We included it to reduce visible fluctuations in the oLED display brightness, when Pulse Pal is powered from a "dirty" power supply (i.e. a cheap accessory charger). With USB power from a PC or laptop, Pulse Pal 2 PCB file v0.5 should have no problems.
