Here's another update with the decoupling coil and pads for TWI sensors
I didn't implement 4 pads for NiMh battery because i think it's useless to monitor individual cells.
No NiMh battery Pack has a balancer connector AFAIK

@dschiedsch

Addition of coil and capacitor for improved ADC-measurement looks good.

Please locate all pads on small side so that soldered cables become unidirectional. Use both sides of double-sided PCB.

"I didn't implement 4 pads for NiMh battery because i think it's useless to monitor individual cells.

Please add 4 pads on 4 ADC-inputs for general use.
( I use my selfmade connectors for NiMH-cells. Single cell monitoring of NiMH-cells with little capacity like 350mAh is usefull.)

Please rotate MS5611 90 degree if possible. Tube forTEK needs little space. 4 little holes, two right and two left of tube, are very usefull for fastening tube with filament before bonding. viewtopic.php?f=86&t=5856&p=83843#p83775

So after a bit of doing here is a new revision
MS5611 is turned 90 deg
I don't have any space left for mounting holes sry

Added two additional ADC pads
All pads are now on the same side of PCB as 1mm test pads
PCB is even smaller 22.6x13.5mm

Hello dschiedsch,
did you get your little boards manufactured?
I guess the design means that the At328 needs to be programmed before soldering.
Any further developments?
Greetings,

Hi
I did get 20 of the original boards made but never made the dlg version because I didn't have the need.
Are you interested in making some?
