Hallo @biologist
danke für deine schnelle Antwort. Hier schonmal die Instructables Sachen:
Es muss nicht beim D32 pro bleiben. Das mit dem SD_MMC hatte ich auch schon gelesen. Habe momentan aber kein micro-SD Breakout da (sind aber schon bestellt). Mit den GPIOs komme ich glaube ich aber aus (habs aber auch noch nicht kontrolliert).
Was wäre denn ein gutes ESP32-Wrover Board? Mit genügend PSRAM für OTA Upgrades?
Auf Dauer will ich mir auch ne Platine dafür machen. Insgesamt gibt es 3 Tonuinos die umgerüstet werden sollen und bestimmt noch ein paar weitere die man mal verschenken kann.
Welche Config Datei meinst du genau?
Hier mal die settings-lolin_d32_pro.h (sollte aber komplett original sein):
#ifndef __ESPUINO_SETTINGS_LOLIN_D32_PRO_H__

/* 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: None so far
Infos: https://www.wemos.cc/en/latest/d32/d32_pro.html
Schematics: https://www.wemos.cc/en/latest/_static/files/sch_d32_pro_v2.0.0.pdf
Caveats: GPIO35 (battery monitoring) + SD can't be changed, it's built in (and because of the SD-pinout used, it is not compatible with MMC-mode)
Status:
tested with 2xSPI: RC522 & SD (by biologist79)

Den nutzt der PCB aus meinem Link ja auch. Man kann halt nur den internen Reader nicht nutzen. Sonst ist da alles fein 
ab 40 nur noch bedrahtet… werde ich mir morgen am Schreibtisch mal ankucken.
