A small breakout for the AMS1117-3.3 linear regulator: feed it 5V (or anything up to about 12V) on the VIN header and it gives a steady 3.3V out, with input and output capacitors and a power LED already fitted. It is the quick way to run ESP-01, nRF24L01, SD cards and other 3.3V parts from a 5V rail. Being a linear regulator it burns off the difference as heat, so it suits a few hundred milliamps rather than a hungry load.
Key features
- AMS1117-3.3 fixed 3.3V linear regulator
- Input and output on 2.54 mm headers, VIN/GND and VOUT/GND
- Input and output capacitors plus power LED fitted
- Rated to 1A, but plan for less without a heatsink
- Needs about 4.7V in for a clean 3.3V out
- Powers ESP-01, nRF24L01 and 3.3V sensors from 5V
