Simple Raspberry Pi 3/4 header for an RGB 64x64 LED Matrix.
Input 5V ONLY! There is no voltage protection or phase protection.
For use with LED Matrixes that have A,B,C,D & E selection pins.
Components needed:
- 2x 74HCT245N
- 1x Molex , KK 254, 6373, 4 Way, 1 Row, Straight PCB Header, 22-23-2041
- 1x Molex, KK 254 6373, 2 Way, 1 Row, Straight PCB Header, 22-23-2021 (SHOULD BE CHANGED TO CONNECTOR WITH HIGHER LOADING)
- 1x 40Pin Raspberry Pi PCB Header
Connections to raspberry pi follow that of the Adadruit-PWN connection pattern:
.output_enable = GPIO_BIT(18), /* Pins 4 and 18 are bound */
.clock = GPIO_BIT(17),
.strobe = GPIO_BIT(21),
.a = GPIO_BIT(22),
.b = GPIO_BIT(26),
.c = GPIO_BIT(27),
.d = GPIO_BIT(20),
.e = GPIO_BIT(24),
.p0_r1 = GPIO_BIT(5),
.p0_g1 = GPIO_BIT(13),
.p0_b1 = GPIO_BIT(6),
.p0_r2 = GPIO_BIT(12),
.p0_g2 = GPIO_BIT(16),
.p0_b2 = GPIO_BIT(23),
