+# ESP32-ETH-CLK-OUT17-SPIRAM
+
+A variant of the ESP32 envelope that supports ethernet. The ESP32
+outputs the PHY's clock on pin 0. This variant furthermore enables
+SPIRAM.
+
+Since Bluetooth and SPIRAM support use some memory, the Toit interpreter
+doesn't fit into the SPIRAM anymore. As such, Toit programs may run
+slower on this variant.
+
+This firmware also increases the partition sizes to 0x1c0000 bytes.
