POWER
About the POWER PCB
POWER is an open source PCB design by Oerdna, published on GitHub under the AGPL-3.0 license. It is a 4-layer board measuring 100 × 100 mm, with 39 components from 18 distinct parts.
Other key parts include the IR2104. By type, the board carries 15 diodes, 8 resistors, 5 transistors, 5 capacitors, 4 connectors and 2 ICs.
It belongs with the test & measurement designs in this gallery.
From the project
Redesigned PCB for simultaneous Peltier control and surface resistance measurement
More details about the device can be understood from the schematic drawing here. The notes are in Russian.
The controller for the complex is STM32L432KC Nucleo.
In this case are studing the I - V characteristic of an element depending on the temperature of the sample. It is important to understand the I – V characteristic near the metal-insulator phase transition (MIT), which is about 68 degrees Celsius. You must understand that the ultimate goal is to stabilize the temperature to a specific value. More about the TEC control [2]
