The effects of the semiconductor shortage

This board is a result of what happens when the semiconductor shortage hits. We were in the middle of a production run of our board Challenger RP2040 LTE when our supplier suddenly decided not to ship our LDO's that we had on order.

The effect of that was that we could not finish the production for these boards. In fact I had to completely redesign the power section of that board since the LDO's were nowhere to be found.

So we ended up with a batch of half produced boards that were of no use to anyone. Except after a little thinking I realized that we could at least sell them without the modem and RF circuitry as a simple RP2040 boards with LiPo charger. The missing LDO was for supplying the modem so without the modem it works perfectly fine.

So here goes, this is a one time thing. We have a little over 100 boards and when they are gone they will be no more, so get'em while they last.

All documentation and instructions are the same as for the Challenger RP2040 LTE, just minus the modem part =).
