The design of Nanosleeper is relatively simple. It is meant to be a development board, so the components on it are meant to represent the minimum for proper operation in the envisioned use case: prototyping ultra-low power systems. Nanosleeper is also...
The PCBs have arrived assembled from JLCPCB and look great! I added the headers and started programming. My goal was to simply demonstrate the ability to achieve
The CosmicPi project uses a very nice chip for biasing SiPMs, the MAX1932. It can be configured to output as much as 90V for powering SiPMs, and you can set the voltage within a programmable range using SPI. It’s not cheap, but it’s very cool.The jumpers...
Out of the box, a Raspberry Pi 4 does not have a real-time clock. When it is booted up, it initially displays the time it was shutdown at - then when it connects to the network, it updates the time via Network Time Protocol (NTP). I fitted a DS3231 real-time...
