AMS1117 DC step down converter (4.5V - 7V -> 3.3V)
thingiverse
A simple bracket / holder for an AMS1117 step-down voltage converter. Converts 4.5V - 7V to 3.3V with max. 800mA current. This converter can be used for 3.3V Arduino or in my case I replace two AA 1.5V batteries of an outdoor thermometer with an external 18650 LiOn cell, a charging unit TP4056 and this AM1117. Made 2 versions: - Version 1 with 5 holes for epoxyd glue or screws - Version 2 with 2 2.5mm diameter holes for M3 screws I attached the FUSION360 files if you like to change the design.
