LED Indicators

The WinLink E850 Development Board has five LEDs.
Two activity LEDs: LED9, LED10
WiFi activity LED –The WinLink E850 Development Board drives this Yellow LED(LED10) via X4, an IO from Exynos 850.

BT activity LED –The WinLink E850 Development Board drives this Blue LED(LED11) via X3, an IO from Exynos 850.

Three LEDs:
The three user LEDs are surface mount Green in 0603 size located next to the micro USB connector. The WinLink E850
Development Board drives the three LEDs from the Exynos 850 XGPIOs;
X1 : XGPIO10/GPG2[2] – Heart beat LED
X2 : XGPIO11/GPG2[3] – eMMC access/write LED
X3 : XGPIO12/GPG2[4] – SD access/write LED
Additional Debug Functionality
