A modern MEGA2560

Overview

The power supply ripple measured so far is about 220mV at the extreme output (5V2A).

test method

The test method uses the ground pin to be more accurate

Instrument: s350 changed to adjustable

ds1054z cracked ds1104z

4R cement resistive load (the instrument is very unbalanced, don’t curse)

2.5w working condition ripple 100mV

Ripple at 5w working condition: 132mV

characteristic;

1. The serial port circuit does not work when the dc socket is plugged in

2. bom minimalist

3. Powerful power supply 5V2A DC-DC 3.3V0.8A LDO (accumulated not exceeding 10w)
