I2C-LCD-driver board hardware design
About the I2C-LCD-driver board hardware design
I2C-LCD-driver board hardware design is an open source PCB design by SolderedElectronics, published on GitHub under the TAPR-OHL-1.0 license. It is a 2-layer board measuring 54 × 22 mm, with 32 components from 19 distinct parts.
Other key parts include the TCA9534PWR, TPS613222A and NMOS-DUAL. By type, the board carries 10 resistors, 5 jumpers, 5 relays, 5 capacitors, 3 ICs and 1 transistor.
It belongs with the displays & leds designs in this gallery.
From the project
Hardware design, BOM, gerbers and 3D files for I2C-LCD-driver-board designed by Soldered Electronics.
This adapter makes connection of LCD to Dasduino (or any other Arduino-compatible board) a breeze! It uses I2C communication which needs only two pins. It can be used and work with all of ours LCDs (16x2, 20x4, 16x4). Use our library and get started in few minutes of work!
It's even easier with easyC - no soldering is needed!
All Soldered Electronics hardware designed in KiCAD, and repositories are organized in the following way:
