LED Matrix Input Module

This is a 34x9 LED Matrix powered by a Raspberry Pi RP2040 microcontroller.

Pre-production Unit

Note that the KiCAD version of this project is incomplete and untested, and is only provided as a reference.

The Atemitech prototype was made and tested, but is missing use of the #SLEEP signal in the current revision. It is not the version that is shipping to customers.

Mass Production Unit

Below are the pinouts of the mass production units.

RP2040 MCU Pinouts

Pin	Name	To	Direction	Config
GPIO0	Sleep	EC	IN	Pullup, low active
GPIO25	DIP1	DIP Switch	IN	Pullup
GPIO26	I2C1_SDA	IS31FL3741	IN/OUT
GPIO27	I2C1_SCL	IS31FL3741	OUT
GPIO28	INTB	IS31FL3741	IN	Floating (unused)
GPIO29	SDB	IS31FL3741	OUT	High active

Test Pads

Pad	Name	Function
TP1	VCC_3V3
TP2	SWDIO	SWD Debug
TP3	SWCLK	SWD Debug
TP4	GND	SWD Debug
TP5	GPIO4
TP6	GPIO5
TP7	VCC_5V
TP8	USB DP	USB 2.0
TP9	USB DM	USB 2.0
TP10	RESET
TP11	SW9
DIP1	GPIO25
DIP2	BOOTSEL

TP2-4 are used for SWD debugging and can be used with picoprobe or similar.

RESET and BOOTSEL are also useful. If RESET is shorted to GND it resets the RP2040. If BOOTSEL is shorted to GND while the RP2040 comes out of reset, it boots into UF2 bootlaoder for firmware update.

IS31FL3741 LED Controller

Documentation and Datasheet of this controller are publicly available.

It drives a matrix of 9x34 (306) LEDs.

Pin	To	Direction	Config
SDA	RP2040	IN/OUT
SCL	RP2040	IN
INTB	RP2040	OUT	Floating (unused)
SDB	RP2040	IN	High active
ISET	27k to GND
ADDR	100k to GND
SW1-SW8	LED	OUT	See table below
SW9	NC		Unused
CS1-CS39	LED	OUT	See table below

The ISET and ADDR wiring results in I2C Address 0x30.

Below is the table describing how the LEDs are placed on the matrix and how they are wired up to the LED controller.

X is the X location in the matrix (from left to right)
Y is the Y location in the matrix (from bottom to top)
ID is the numerical identifier of the LED
Address and Page describe the memory location in the IS31FL3741's registers
SW and CS are the pins

Please refer to the controller's datasheet for additional information about how to program it.
