It was always under my nose, but I never realised it was there. Thanks for the tip!

As a first step, I would recommend checking out osm.org from a computer. Once logged in you can use it as an editor straight from the browser. The embedded documentation really helped me initially.

Nice! Could you explain what it is or where to find more information about it? I was not able to find information online

We are working towards having a product properly packaged. This is a prototype that is not mature enough yet to justify the cost/time to package it. Moreover, this custom chip is used to measure ultra low currents (down to femto amps), so any packaging could potentially interfere with the measurement capabilities (-> no epoxy). It is however protected by a large shielding box, but it's no use during assembly/modifications :/

The little gray wires should be all nice and straight. Even though your chip may be a good boi, touching it will wreak havoc on the wire bonding. Repairing the damage shown on the picture takes a skilled worker and very expensive equipment. Even then the repair is not fully guaranteed to be successful.
