Lamoka1/2 PCB
Lamoka1/2 PCB is an open source Raspberry Pi PCB design by bearjhartjen: a 2-layer, 122.7 × 124.8 mm board with 126 components (73 distinct parts). It is built around the INA240A2DR, RP2354A, AMS1117-3.3, SN74AHCT1G125DBVR and more. Filed under power & battery and sensors.
Inverter/Charger Project managed by Flamingo and Cactus
For the Owego Rotary craft fair, taking place at the Elks lodge in Owego, NY, on November 14th from 9am to 3pm, the main project being presented by Flamingo and Cactus will be the Lamoka1/2, a inverter only version of the Lamoka1. More details will be presented after the event.
The Lamoka 1 is an open-source inverter/charger system designed for complete transparency and control. Unlike market alternatives that are locked-down black boxes, the Lamoka 1 gives you full access to your power conversion. If you don't have technical experience, that's completely fine—our Portal Interface Engine…
