Ethernet

atopile·cell-sim·elec/layout/ethernet/ethernet.kicad_pcb

Ethernet is an open source PCB design by atopile: a 2-layer, 33.2 × 17.3 mm board with 32 components (26 distinct parts). It is built around the C2913205, C139797, C709357. Filed under power & battery.

This cell-sim is designed to mimic a LiPo battery pack for develpoment of the surrounding electronics, like a BMS.

- 16 channels - Open-Source hardware design, you can embed onto your own HIL setup - ⚡️ 0-4.5V and 0-500mA per channel - DMM muxed to each channel for arbitarily precise measurment - Open-circuit simulation on each channel - 📏 16bit ADC feedback for voltage and current - 🔌 USB w/ Python software interface (+ 100MBit Ethernet + WiFi waiting for firmware support)
