README
README.mdCosmicPiV2.0b
Version 2, beta production of the Cosmic Pi, learning the lessons from V2.0alpha and adding back the UART connection between GPS and STM32. All the components are now on a single PCB with a snap-off for the SiPM elements. SiPMs are now from Broadcom, as they purchased Ketek's SiPM production unit.
The design uses scintillators from Amcrys http://www.amcrys.com/ which are not yet available via a retail outlet, however any BC-408 equivalent scintillator that has diamond polished finish surfaces and dimensions of 200x100x10mm can be mated to the SiPMs with suitable mounting holes.
What do the signals do?
