Fair enough! What we don’t know is how tolerant the LarkBox Pro is to minor voltage variations. The power supply puts out 12.1 volts, and a maximum of 2 amps. Well after some quality time with the fluke, the great mysteries of the universe have been revealed. A source like the PowerFilm Lightsaver Max. 😃 In this case the shortcut is good for off grid use or battery power, since the LarkBox Pro simply requires a stable 12 volt source. How our Chinese friends love their engineering shortcuts. I would recommend NOT using this supply to charge your flagship smartphone, tablet or Macbook Pro. It seems the pins are wired correctly in the connector, but there is no data or logic along with it. In reality, it is just a 12 volt 2 amp power supply, delivering its power to a USB-C connector. The Power Supply supplied with the LarkBox Pro has a USB-C connector, but that is as close as it comes to being USB-C compliant. This is why my Anker USB-C PD adapter didn’t know what was going on with the LarkBox Pro. Another interesting feature was what we thought at the time, was power over USB-C PD, which turned out to be fake (underutilized :)). The LarkBox Pro was interesting because of reasonably powerful CPU, low power draw, and small size.

Skip to 09:30 to go right to the relevant place on the timeline. It was introduced to fill in where the raspberry pi couldn’t fulfill all of our communications requirements.

Recently the Larkbox Pro from Chuwi was introduced on the channel, as an effective low power yet capable mini PC for ham radio field communications.
