v1.0/1.1 Board

For working Ethernet on board V1.0 and V1.1, EthClockMode 3 is needed as included in the following template. This template also enables the card reader.

The advertised “Downloader Expansion Board” is not necessary for flashing. The six contacts near the product name on the backside are:

1. 3V3 (top most in the picture above near the ESP32)
2. GND
3. RST
4. IO0
5. RX
6. TX

The card reader uses these pins for communication:

GPIO	Function
02	MISO
12	MOSI
13	CS
15	SCLK

So if you need the card reader in your project, three pins of the 2x8 header are already in use for SPI!
