2. Pin definition

The BL-62B module has 16 pins in total, as shown in Figure 2.1.

Peripherals include 13 GPIOs, 1 SPI master/slave, 2 UARTs, 1 I2C

master/slave, 5 PWM channels, 5 12-bit general-purpose ADCs, 1 10-

bit general-purpose DAC, 1 SDIO2. 0 slave, 1 IR remote hardware

accelerator, etc., UART can be flexibly configured. Each GPIO can be

used as a general-purpose input and output function. The LED on the

module is controlled by IO0, and whether it needs to be controlled is

determined by the customer. Table 2.2 is the interface definition.。
