The Factory | PiicoDev Transceiver: Radio Wave & Data Packets

- Here's a game changer! We've kept the lid on the PiicoDev Transceiver project pretty well, but we're finally ready to talk about it. The PiicoDev Transceiver is a 915MHz packet radio. Radio modules don't usually have an I2C interface, so this module uses a microcontroller to act as a go-between: interfacing the SPI radio to the I2C bus and handling commands and messages. You might notice the diminutive size - we've managed to squeeze the antenna onto this board so no additional RF hardware is needed. This episode is all about how we managed the compact design, and a real field-test to see what this baby can do!

So cool to see the background story of this neat device. Great job team Core Electronics!
This is glorious! Well done on such a goodly piicidev module
It seems like it would be useful on a small farm. I can see them reporting greenhouse conditions to a central controller that then makes the appropriate response. I think you could take a lesson from the ham radio community and build a repeater module. Place the repeater (with a GOOD antenna) up high and let all of the node modules send messages through the repeater. You'd need the ability to set different transmit and receive frequencies, but the increased range would be worth it.
Very good 👍
Very cool. Why didn’t you use UART isn’t that easier the I2C? Not a criticism just a question.
It would be cool to have the option to have an external antenna
I'd like to see some range tests using external omni-directional antennae and the same with directional antennae.
no way to attach that without destroying the current antenna i guess
I have three humidity controllers on my machinery that run on an arduino board, being able to monitor these units from inside my house would be fantastic . Modifying the sketch i have for the dehumidifier to run on a piico would be easy enough.
Awesome.. Can think of a few things to make use of this.
With my experience with 900Mhz though, getting the transmitter and receiver up high. I do wonder is there enough power to manage multipathing. Be interesting to see if you can set a full-duplex signal between multiple devices as well.
Perhaps they need a repeater module.
So how would these compare to the T-Beam LILYGO? Those can go out beyond 100kms, so I’m wondering if there is a thought of adding an external antenna?
hey core electronics I would like to do something similar with this transceiver by using a sensor module to send its data across too another module with some output devices, would there be a way to adapt this code to that kind or project and if so how?
What if you increase the fresnel zone by putting the transmitter up higher?
Also can you place else if arg that does an fractional error retry if the packet is incomplete and throw out incomplete packets and see if you can get further without packet errors?
Could a second transceiver be used as a repeater to extend the range?
Sure! you could just read a message in and re-transmit it
Fun
We get signal!
What?
It's you.

Any reason other than pure greed that the January shipment of pi 4's is going directly into your hugely marked up kits rather than being sold as is?
