ESP32 PinPulse Shield, 24 GPIO LEDs

A base for the ESP32 with an LED on every GPIO, so you can see each pin go high or low without a meter. The board plugs into the two black sockets in the middle and every pin comes out to a 2.54 mm header with its own LED beside it. Four 74HC04 inverters drive the LEDs, so they cost your pins nothing. Highlights 24 GPIO LEDs. One LED per GPIO, driven through SN74HC04 inverters so the LEDs do not load the pins. Pin strips on both sides. Four 15-way 2.54 mm headers with the pin names printed beside them. 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. In the box 1 × ESP32 PinPulse Shield, headers fitted The ESP32 board is not included.
