The idea was to drive a LC with 4 (2×16 characters) LCDs to have the optimal spreading of the names & values on the 8 Channels, so use for a pair of 2 Channels 1 LCD ;)
!! IMPORTANT NOTES !!
If you get strange reboots or the LCDs wont work correct, remove Resistor R10 !
Also if you have 4-bit LCDs, dont connect D0 - D3
