Ydrp2040 Schematic _hot_ Jun 2026

Two 18pF to 22pF loading capacitors are connected from each pin to ground. A 1MΩ resistor is placed in parallel with the crystal to bias the oscillator inverter. Keep the crystal traces as short as possible and avoid running high-speed digital signals underneath it.
