About the TougherPowerMonitor-HW PCB

TougherPowerMonitor-HW is an open source AVR/Arduino PCB design by ahillbom, published on GitHub under the MIT license. It is a 2-layer board measuring 130 × 53 mm, with 75 components from 25 distinct parts.

Its main chip is the Arduino_Nano_v3.x, from the AVR/Arduino family. Other key parts include the AP63205, TPS1HB08A-Q1, FeatherWing and INA3221. By type, the board carries 26 resistors, 23 capacitors, 11 connectors, 8 diodes, 4 ICs and 1 module.

It belongs with the sensors and test & measurement designs in this gallery.

From the project

Triple-channel power monitor based on INA3221 and TPS1HB08A with some filtering for tougher conditions. Compatible with Arduino Nano and Feathers.

Power monitor with three channels, each capable of continuous 10A and 24V. It is compatible with both Arduino and Feather, and is based on a popular INA3221. The power monitor is more robust compared to other modules based on this IC. Each channel has proper RC filtering with TVS diodes to prevent INA3221 from being destroyed by transients, and to eliminate glitches. Pluggable screw terminals are rated for 15A, and can handle 12 to 30 AWG wires.
