Hi there,
I have a few questions about the Tachyon board.
First, I was wondering what the pogo pins are used for on the board. Also, can you confirm whether the Tachyon is FirstNet compatible?
In my application, I plan to hardwire Ethernet, and it looks like this can be done using a USB-C to Cat5 adapter?? What kind of backend configuration is required to make that work?
Lastly, can I attach a standard Raspberry Pi HAT to the GPIO pins? Does the Tachyon have the same 40-pin layout and functionality as a Raspberry Pi?
Thanks for your help,
Where do you see pogo pins? There are some underneath the cellular and Wi-Fi antenna module if you've looking at a disassembled picture.
Yes, you can use Ethernet over USB-C. You enable it the normal way you would for Linux. The Particle cloud side does not require any special configuration for this to work.
The 40-pin header is mostly compatible with the Raspberry Pi, see 40-pin header.
The Tachyon cannot out of the box connect to FirstNet. It does have an eSIM, so if you have a provider that can provide a SIM profile via RSP URL it could work. However, any FirstNet provider will almost certainly require additional certification, probably PTCRB and possible others, which will be complex and expensive.
@rickkas7 I've tried getting the realtek dual 2.5Gbps PCIe hat going and I don't think it will work even with the updated Ubuntu 20 kernel. I believe it's the 8125 chipset. Any tips on getting it to work or will I have to wait for a more current kernel?
Oh, so the section of the board highlighted in the picture is the Cellular/Wi-Fi antenna?! Very cool
Also, I’m looking to add a relay HAT to the board like I’ve done on a Raspberry Pi in the past. Are you saying it should work, or would I need to reconfigure any of the pins or settings to make it compatible.
Thank you
Hey, from the mapping Rick mentioned:
I would check if your pins match:
Best,
