How much power does the 2.8” Display use assuming maximum brightness? I noticed my Pico core temperature goes up by about 5 degree Celsius with this display so I have added a heat sink but I’m concerned if I’m going to run into power issues when I’m using other peripherals.
Pimoroni does not provide a datasheet, but similar displays are rated at about 250mW (3V3 logic, 80mA backlight LED current). And in the schematic you have a APA2502 driver chip with four channels, 20mA each so this figure seems to be in the right ballpark.
Regarding power issues: yes, could be. This depends on the regulator on the board. The Pico familiy provides a maximum of 300mA, some other boards (e.g. the Pico Plus family from Pimoroni) have a stronger regulator. But for some additional sensors a Pico should be enough.
