Description

The PinPulse shield for the ESP32-S3: an LED on every GPIO, so you can see pin states as your code runs. The ESP32-S3 board plugs into the two black sockets in the middle; every pin comes out again at the edge.

Highlights

36 GPIO LEDs. Driven through inverter chips, so the LEDs show HIGH and LOW without loading SPI, I2C, UART or PWM signals.
Pins and sockets. Every GPIO has both a male pin and a female socket, taking any jumper wire.
Display port. A 15-way FPC connector links Lonely Binary TFT, E-Ink and touch displays with one ribbon cable (displays sold separately).
Four mounting holes for a case or a baseplate.

Smooth operation across the board

Nice three pack. Used all three and they work well.

Wrong part sent

The wrong part was sent, 4MB version sent, I ordered 16MB. I emailed the company last Wednesday July 1 and have heard nothing.

Appriciate the quality and service from Lonely Binary. Second time purchasing from them and wont be the last. As a beginner in electronics world, their website has helped me a lot. Not many places you can find the required information, explanation and the materials you need at one spot. Keep up the good work lads.

Screw Terminal Boards

I started by emailing the company wasking for the standalone screw terminal boards for the ESP32-C3 . I really hope you start stocking them stateside, but thank you for shipping them so quickly and listing them on your site as well.
