/* This is a develboard-specific config-file for *Wemos Lolin32*. Specific doesn't mean it's only working with this board.
Lolin32 is the predecessor of Lolin D32.
PCB: https://github.com/biologist79/Tonuino-ESP32-I2S/tree/master/PCBs/Wemos%20Lolin32
Infos: https://arduino-projekte.info/wemos-lolin32/
Caveats: None
Status:
tested with 2x SPI, RC522, SD (by biologist79)
tested with 1x SPI, PN5180, MMC (by biologist79)
