About the EmoePower PCB

EmoePower is an open source PCB design by emoestudio, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 82 × 52 mm, with 68 components from 38 distinct parts.

Other key parts include the LM5175PWP, MAX4080T and MAX907. By type, the board carries 19 capacitors, 17 resistors, 4 transistors, 4 connectors, 4 diodes and 3 ICs.

It belongs with the power & battery designs in this gallery.

From the project

A DIY Buck-Boost Power Supply for Laboratory works and personal use, based on LM5175 and ESP32.

This is a pocket-sized, IoT-ed Power Supply.

It's final goal is to meet EEers' daily usage requirements:

- Small Sized - Programmable Voltage and Current settings - High Efficiency - High Reliability - High precision - Multiple control method - Modernized GUI

This project is still under development and test.

Finally get Rt = 84.5kΩ and we select standard value, that is 82kΩ.
