PinPulse LED Shield for Nano, 22 Pin Status LEDs

A shield for the Nano that puts a status LED on every I/O pin. See which pins are HIGH or LOW at a glance, for learning Arduino and debugging circuits. Highlights See every pin. 22 LEDs show the state of TX/RX, D2 to D13 and A0 to A7. Buffered LEDs. Five SN74HC04 inverters drive the LEDs, keeping the load off your I2C, SPI and UART signals. Male and female on every pin. Dual 2.54 mm headers take any jumper wire type. Labelled. Pin names are printed on the top, and the bottom carries an SPI, I2C, UART, PWM and ADC pin map. Arduino IDE compatible. Existing Nano sketches and libraries work as they are. In the box 1 × PinPulse shield The Nano board is not included. Specifications Fits: Nano V3.0 (ATmega328P) LEDs: 22, one per pin (TX, RX, D2 to D13, A0 to A7) LED driver: 5 × SN74HC04 hex inverter Headers: 2.54 mm, male and female on every pin Works with Nano V3.0 boards and the Arduino IDE.
