About the S3 SHARP LCD Controller PCB

S3 SHARP LCD Controller is an open source ESP32 PCB design by martinberlin, published on GitHub under the MIT license. It is a 4-layer board measuring 77.9 × 45.2 mm, with 60 components from 39 distinct parts.

Its main chip is the ESP32-S3FN8, from the ESP32 family. Other key parts include the RT9080-33GJ5, USBLC6-2P6 and TP4057-42-SOT26-R. By type, the board carries 17 resistors, 15 capacitors, 7 connectors, 7 diodes, 4 ICs and 3 transistors.

It belongs with the displays & leds designs in this gallery.

From the project

This KiCad board aims to be a low consumption driver for SHARP LCDs w/optional touch. MCU: Nordic RF52 (not tested) | ESP32S3 buy one in Tindie before sending to production

The goal of this PCB is to make a small SHARP memory in pixel (MIP) controller All this might change as the idea develops but initially the plan is the following:

- DS3231 or RV2032 acting as RTC to generate the Squarewave required by this displays - Optional touch only available in eBay from a seller in the UK (Better use 1.1 version)

S3 SHARP LCD Controller: common questions

What microcontroller does the S3 SHARP LCD Controller use?

The S3 SHARP LCD Controller is built around the ESP32-S3FN8, from the ESP32 family.

How big is the S3 SHARP LCD Controller PCB?

The S3 SHARP LCD Controller measures 77.9 × 45.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the S3 SHARP LCD Controller?

60 components, from 39 distinct parts. The full bill of materials is listed on this page.

Where can I download the S3 SHARP LCD Controller design files?

From the martinberlin/Sharp-LV repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the S3 SHARP LCD Controller design in my own project?

Yes, under the terms of its MIT license, which martinberlin chose for the repository.

Can I test firmware for the S3 SHARP LCD Controller without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
