Use Raspberry Pi GPIO pins with SenseHat attached

[@super35media]

Actually, one last thing...I just found out that you ALSO have to have the I2C eeprom pins connected. That's pins 27 and 28. Without those, the hat is connected but address 0x46 does not show up when you run i2cdetect. FINALLY IT WORKS! I now have a PWM controller and the raspberry pi sense hat running off the same i2c pins

This simple little trick is so important. Thank you alot

[@Pi-Tutorials]

levelemup glad it helped.

Thanks for the info about these connectors. I did not realise that they came apart.I've been using a Pimoroni Black HAT Hack3r for access to the unused pins on my HATs for some time and this work really well with the connectors which do not pull apart.Tony Goodhew

Glad I could help Tony. When I discovered it came apart and it was possible to put an extended header in place I thought it was too good not to share.

My sense hat adapter for Pi 400 has two double rows of pins. Only one of them accommodates the sense hat. Before reading your post, I didn't understand why the adapter had 2 sets of pins. Now I suspect that the pin set not occupied by the sense hat could be used for the breadboard adapter without the need for taking my sense hat apart. Have you tried that?

[@sebastiangerety8726]

you are the man. thank you!

[@mohammedfazil3473]

Which raspberry pi model you are using ?

[@louisparkerson6485]

If you use jumper cables to connect the needed pins you don't have to have the sense hat directly on top of pi, solving the problem of the temperature sensor being inaccurate as it is directly on top of the CPU.

[@timsullivan7692]

What a bloody good idea! I'm doing this now because the temperature readings are useless!

[@floridian080]

On the pi400 with adapter, the hat does not sit over the computer. Also, the pi400 generates very little heat.

[@FrancoisSchnell]

Very useful, thanks for sharing!

[@c.i.t.techclub]

Excellent, Thanks

[@UUGear]

That looks great and will be very useful! I wonder how tight the surface mount header on the front side could hold the extended header? When you try to take your SenseHat off from your Raspberry Pi, will the extended header get detached from the SenseHat board?

[@Pi-Tutorials]

Generally the header pulls off the Pi rather than from the Sense Hat, but that is how I discovered it was removable. Once when removing the Sense Hat from the Pi the header pulled out a little, exposing the pins.

[@UUGear]

Thanks for sharing :-)

I tried using two GPIO jumpers to connect the hat to the pi and it did not work. I also tried connecting power and ground GPIO jumpers but it still dod not work. Any ideas why?

[@super35media]

Actually i just figured it out. The Gpio pins that are used are the 5V power, the 3.3V power, the two I2C ports, and any ground.

[@Pi-Tutorials]

Nick the Drone Guy are you trying to connect the sensehat to the Pi with jumper wires. It uses 4 pins. Physical pins 1, 2, 3 and 5. See this page pinout.xyz/pinout/sense_hat

[@super35media]

Keith's Pi Tutorials that is where I figured it out. my problem was not realizing it needed both powers in.

[@Pi-Tutorials]

Nick the Drone Guy you also need a ground. Sorry, forgot to mention that.

[@super35media]

Keith's Pi Tutorials well yeah. i just thought that it needed one of the power pins not both. I'm an idiot. ;-) Good video though! I need one of those GPIO pin extensions

[@louisparkerson6485]

Good job

[@louisparkerson6485]

Could someone please tell me the numbers of the GPIO pins used as I cant understand all the complicated schematics

[@louisparkerson6485]

Don't worry I found out.

[@gspacec7772]

And which numbers?

[@ajayjoseph4626]

nice one!

[@louisparkerson6485]

Does anyone know if the sense hat uses all the the pins

[@louisparkerson6485]

All the ground pins not the the pins!

[@Pi-Tutorials]

King Balloonion not sure, do a continuity check with a multimeter across all the ground pins on the sense hat, if they are all connected you only need to connect one of them to the Pi.

[@louisparkerson6485]

Thx
