Kris Winer writes on Maker.io about his new design:
This is a small development board for the ESP8285 (ESP8266 plus 1 Mbyte embedded SPI flash memory) which includes an FTDI FT230X USB-to-serial converter so Arduino programs can be flashed via the USB Micro-B connector. The board has a MAX1555 LiPo battery charger, a 3.3 V MIC5528 LDO supplying 500 mA for plenty of power, has reset and boot buttons for easy programming, has a blue led on GPIO15, green led for power on, red led for charging indication, and yellow and orange leds for RX/TX.
Available for $24.95 on Tindie.
