http://www.calao-systems.com/articles.php?lng=en&pg=6099 this daughter board add the following device: - Micro-SD socket - TTL 3V3 - (Tx/Rx/RTS/CTS) - I2C port - 0.96" Serial OLED Display Module (over UART) - MP3 decoder with Micro & Speakers - 4x PB, 4x Leds (Blue), 3x Leds (Green, Orange, Red) for now we add only the 2 UARTs, 4 Buttons, 7 leds and i2c via DT used_led1 will not be re-add via DT as it's used by the motherboard too Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
