Waveform Generator Design with ESP32

flux

Here’s a minimal parts list to pair an external 12-bit SPI DAC with your ESP32 for sine/saw/tri/square/multi-sine generation:

Table

RefQtyPartNotes
U11MCP4921-E/SN12-bit SPI DAC, SOIC-8
C11100nF0603VDD decoupling (X7R, 50 V)
C21GRM21BR61H106KE43LVDD bulk decoupling, 10 µF 0805 (X5R, 50 V)
R11RK73H1JTTD1002F10 kΩ 0603, 1% — DAC output filter resistor
C31100nF0603Output filter cap (together with R1)
Next, we need to place the ESP32 itself. Which variant do you prefer?
  • ESP32-S2 or ESP32-S3?
  • Do you want to use a pre-mounted module (e.g. WROOM/WROVER) or the bare QFN chip?
