Barrel Power
Barrel Power is an open source PCB design by SoukeyCircuits: a 2-layer, 30 × 79 mm board with 8 components (5 distinct parts). It is built around the BD80GC0MEFJ-ME2. Filed under science & space.
Arduino based NMR spectrometer for use in low field applications.
Barrel-jack version of the Power-USBC board. The PD negotiation and interlock are gone. It takes a DC input on J1 (PJ-058B), makes the +8 V (BD80GC0VEFJ-ME2) and +3.3 V (BD33GA5WEFJ-E2) rails, and feeds the main board over the same J2 (1×12) and J4 (2×5 right-angle) connectors.
Not yet built or ordered. The input voltage range hasn't been confirmed against the regulators; check the BD80 dropout before choosing a supply. IC25 is out of stock at JLC, so hand solder it.
