IOTTeach
About the IOTTeach PCB
IOTTeach is an open source PCB design by SonDinh23, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 55.3 × 60.4 mm, with 60 components from 28 distinct parts.
Other key parts include the TPS54202DDC. By type, the board carries 14 connectors, 13 resistors, 12 diodes, 11 capacitors, 3 transistors and 2 relays.
It belongs with the displays & leds and test & measurement designs in this gallery.
From the project
IOTTeach is a detachable plug-in kit designed for hands-on learning, quick hardware validation, and classroom labs.
IOTTeach is a detachable plug-in kit designed for hands-on learning, quick hardware validation, and classroom labs. It exposes common peripherals (relays, RGB/status LEDs, buzzer) and standard 2.54 mm headers for power, analog, and digital lines so students and developers can prototype with any MCU or SBC without soldering a custom shield.
Design philosophy: Bring Your Own MCU — connect any microcontroller (ESP32, STM32, Arduino, Raspberry Pi Pico, etc.) using Dupont wires.
