Additional parts not in the BOM file: ATTINY841 and LM4040BIM3-2.0/NOPB
100-ppm/°C precision micropower shunt voltage reference 3-SOT-23

Code to use Arduino ISP as programmer:

; PlatformIO Project Configuration File
;
; Build options: build flags, source filter
; Upload options: custom upload port, speed and extra flags
; Library options: dependencies, extra library storages
; Advanced options: extra scripting
;
; Please visit documentation for the other options and
