+## Generic ESP8285 modules
+
+ESP8285 ([datasheet](http://espressif.com/sites/default/files/documentation/0a-esp8285_datasheet_en_v1.0_20160422.pdf)) is a multi-chip package which contains ESP8266 and 1MB flash.
+All points related to bootstrapping resistors and recommended circuits listed above apply to ESP8285 as well.
+
+Note that since ESP8285 has SPI flash memory internally connected in DOUT mode, pins 9 and 10 may be used as GPIO / I2C / PWM pins.
