You will need a dc-dc boost converter for usb 5v output.
I plan to use it for connecting 3.3v usb wifi module.

Thanks for the response. Of course you need 5V for usb. I ordered some step up converters.
Doesnât the mipi connector also support a camera?
Probably? Iâm honestly not sure.
I look forward to seeing the modifications you make. I donât really know how to safely supply additional power, or what extra hardware might be needed or how it would need to be connected.
In researching a little, the Luckfox Pico does but the Lyra does not.
thanks - just ordered the board .. will arrive next week .. ish..
Does this img have audio? I canât hear any sound
Currently no audio support. I wrote a simple audio driver, using soft pwm. But the sound quality is very bad. If I connect rmio pins to PWM_L and PWM_R, I may make it work.

Measured power consumption with no battery, default screen brightness, no keyboard backlight.
Idle: 0.509~0.524w
prboom: 0.587~0.604w
Esp32C3 wifi connected: 0.626~0.85w

Hello all, how can you connect to the internet with this (to install or update apps). Maybe via a pc serial link? Or does the wifi module mentioned earlier works for this? Where would one get such module please (maybe on aliexpress)? What is the model number? Thank you!
Hi, I have tried the USB Connector with a boost converter. It works with a USB Drive, but Wlan dongles are not detected. Could it be that the driver for Wlan is missing in the build I down loaded this week?
That is the result of my soldering.
I also have to cut the case to make room for the connector, is not that bad.

Could you share the information about the âboost converterâ? (I donât really know much about hardware.) I bought a connector, but it will only have the Lyra port on one end and the female USB-A on the other.
I wonder if there would be a way to (safely) tap into power somewhere on the PicoCalc, and use one of those old USB cables that could supply power from another USB port for some external drives, etc.?
I was hoping to use it for a wireless dongle too. Iâm hoping after some experimentation that someone creates a solution that is easily sourced (or made) for those of us who donât tinker in hardware very much. The Lyra seems like an excellent module for the PicoCalc, but without wifi/bt, itâs not very useful.

This is the converter I used:

I plan to try rtl8188ftv 3.3v usb wifi module. This module is very cheap. According to the datasheet, the current consumption is about 220ma~350ma.
If you can share the pid/vid of your usb wifi adapter, I may complie the driver for it.

I am just waiting for my Lyra so i can get this going.
