Can the power supply of pi-topCEED be replaced with 18VDC @ 3.0A?

The official power supply provided by pi-topCEED is 18VDC @1.0A. However, the product specifications on the website state that the power supply requirement is 18VDC @ 3.0A (Max). I would like to ask the administrator to confirm whether pi-topCEED can indeed use a power supply with a specification of 18VDC @ 3.0A.

If possible, considering that the pi-topCEED frequently displays low-voltage warnings when used with a Raspberry Pi 5B, I would like to know whether upgrading the pi-topCEED’s power supply to 18VDC @ 3.0A would resolve the voltage insufficiency issue, while also ensuring that the Raspberry Pi 5B will not be damaged.

No problem powering CEED with a higher wattage power supply. It may help the low voltage messages, but it may be the physical cable from the CEED hub to the header. You will see that the +5V and ground on the GPIO Header are larger AWG cables connected to a two-pin connector on the hub. It “MAY” be worth getting a short USBA to USBC connector with decent size cable and use the USBA connector on the HUB (you should disconnect the small two pin connector ) The chip they use on the HUB can supply 5V @ 3.5A. The Pi5 will always complain about the power supply not being sufficient because it’s not PDR compliant and will reduce the power available on the Pi5 USB connectors. (You can disable this function in the operating system) Another thought if you have the pi-topPROTO breakout board, is that the 18V is available, and you can buy small buck converters that support PDR, I’m going to try one at some time in the future…image
