Regarding the output of the LPRO-101, it has series resistors of two times 10k inside, so we added a shunt of 4k. This guarantees, that the analogue inputs of the Atmega stay below 2.5V. None of those measurements are time critical, so running at 1 MHz is absolutely sufficient. The circuit was realised on a double sided pcb.
