## Description

RPi GPIO Status LED & Terminal Block Breakout Board HAT for Raspberry Pi A+ 3A+ B+ 2B 3B 3B+ 4B : desertcart.in: Computers & Accessories

Review: Excellent for Debugging and Clean Wiring – A Must-Have for Pi GPIO Projects
Review: Easy to use

## Features

- The item has been soldered and assembled. Support for Raspberry Pi A+ 3A+ B+ 2B 3B 3B+ 4B
- GPIO status LED and power 5V / 3.3V indication. GPIO output or input level high LED on, output or input level low LED off. 5V blue, 3.3V red, GPIOs green. The position of the LED is in a one-to-one correspondence with the position of the Raspberry Pi 2x20pin connector, and the logic level of the GPIO can be observed very quickly and intuitively. The driving current of each LED is only 0.1mA, so you don't have to worry about it affecting the read and write status of GPIO.
- Terminal block pitch 3.5mm/0.138", wire size range 26AWG to 16AWG, strip length 5mm, screw M2 steel, pin header and cage copper. 2 x 20 pins expansion pin header, height 8mm/0.32".
- Packing list: 1x terminal block breakout module, 4x M2.5x16mm nylon standoffs, 4x M2.5x6mm nylon standoffs, 4x M2.5 nylon nuts(NOTE: the item not include Raspberry Pi Board).

## Questions & Answers

**Q: has this been tested with POE hats or any other existing hats?**
A: I originally installed a 3 relay contactor hat, but quickly grew out of that. I had to upgrade the power supply (Mean Well MDR-60-5) to 60 watts which powers the Pi (bypassing the micro USB port), 16 relay contactors (not all used), 8 sensors, and 4 3.3v step down regulators. The Pi is not a very good power source, especially 3.3v. All the gear is mounted on C45 DIN rails to avoid breadboards. All wire junctions are screw down like the this hat. Also the LEDs were very helpful in debugging. The code and it's relationship to the GPIO is quite complex. Latency and hysteresis were an ongoing challenge. I wouldn't cover the LEDs with another hat.

**Q: According to diagram, the posts appear to be one way (diode) from the gpio head. can i send signal back to the pi from this breakout?**
A: The diode is a led.  Set the GPIO pin of your choice to output and the led will show the state of the output of that GPIO pin.  Set the GPIO pin of your choice to input and the led will show the state of whatever is input to that GPIO pin.

**Q: What are the length and width of the connector that fits onto the 40-pin header? I want to see if it will fit through the slot in the top of my case.**
A: This is not the answer I was looking for. I would like to see if I can use this breakout box with the cover installed on my Raspberry Pi case. It has a slot 55 mm long X 8 mm wide. Will the header connector fit through this slot?

**Q: Will it work with Pi Zero W?**
A: Yes, the item can support Pi Zero W, But only two screw holes can be fixed.
