L511 Evaluation Board (silkscreen L506_EVB ) Is specially designed for developing L511 serial module, To help developers to develop, debug, test L511 series 4G IoT LTE module. Below and mark shows L511 the main functions of the development board. In this article, we will in the subsequent chapters on the function of each part is described.
The below picture description:
1. The L511 USB port is on the EPI board, not on the EVB.
2. The power switch S2. This switch S2 can switch the corresponding power input way, Choose an external power adapter or direct bonding wire by external input 3.8 V dc power supply.
3. DB9 UART is serial port for module AT instruction, same as USB uart.
4. USB for Debug UART is used for user to retrieve the Debug information.
5. To facilitate the user's use, maintain a minimum system and we provide a power interface on the L511 EPI board. LYNQ C
