Final V1.0 Production Version

Finalising the V1.0 Production Version.
Generationg the gerbers and the BOM

Adding Battery measurement and power on led. Cleaning up silk screen.

Connecting both terminals of the battery to adc pins of the uC to measure the battery capacity. Adding the connections of the power-on led that is build in to the button.
Cleaning up the component names of the silk screen.

Adding some missing uC connections.

Adding some connections of the uC that were missing before.

Finish Layout, document schematic with blocks

Routing the last connections of the layout. Starting with the naming on the top panel.
Documenting the schematic by adding functional blocks and descriping them.

Finishing Schematic, Starting with Layout

Finishing and cleaning up the schematic, but also replacing some components and optimizing some footprints, for example the ATmega.
Starting with the PCB Layout - placing the components, wiring up the power circuit and the power cuircuit.
Adding an excel file, which shows the data of the chosen values of the current shunt resistors.

Current Sense Schematic, Switching a few components

Working on the current sense schematic. Cleaning up some other parts. Switching a few components/footprints - primariliy the footprint of the oled screen.

finish boost circuit, start reverse surface mount led

Finishing the boost converter circuit and selecting the inductor and the schottky diode.
Starting with the footprint of the reverse surface mount led.

Parts in lib, parts of the schematic

Creating the footprints in the library for the used parts. Starting with the schematic.
