RTL-SDR Extension Board with USB HUB and RTC

Only if there are still some samples left after the beta test.

Anxiously waiting for this to get into production.

ya… I was looking for the parts to add the internal usb 2.0 hub / RTL-SDR, but this project gets me thinking I will wait for an expansion board instead.

Did the beta test boards go out and how are they performing?

A few beta test boards will be sent out this Friday. The performance is the same as the RTL-SDR Blog dongle V3.

It goes a little further. Now GPS and LoRa are supported.

That is awesome!!! I will be waiting to get one of these vs. modifying my Uconsole. Thank you for this amazing project.

Great news! I cannot wait to see this come to fruition!

Is the LoRa radio connected with UART or SPI? The reason I ask is I’m interested in using it for Meshtastic and Meshtastic only supports SPI.

We shared the same thoughts. The Lora module connect to the SPI1, and Uart for GPS. Using meshtastic on uConsole is the major reason that I added the LoRa module to the extension board. I ‘ve test the meshtasticd on uConsole and it worked great.

I’m curious to know how you did it. When I was looking at schematics it looked like the SPI GPIO was split between the minipcie connector and the flat-ribon connector.

I’m looking forward to this board as much as I did for the uConsole. Meshtastic will be a fun addon.

I have not looked closely at the flat-ribbon connector yet, but the mini PCIe connector has the SPI1 fully exposed. For Meshtastic, all you need to do is change SPI0 to SPI1 in the config file.

I will send the beta test board in the next 2 days, kinda busy with other work last week.

This is getting more versatile by the day. Getting super excited for it to go into production.

希望不久将来,它能够出来成品,天线的地方能够内置或者外壳可以有孔位置可以安置天线

噢~!它的天线好像有点多,这样应该不会很方便吧。

How do I get on the waiting list?
