Notes：
(1) words in black color is the common pins in both A and B, words in blue color is unique pins of B module.
Compare to A module, EMW3080V2(B) has four pins: PIN 7, 8, 9, 10 with function: traffic control of UART,
SPI function, PWM output and GPIO.
(2) PIN 19 is used as BOOT，PIN23 is used as EASYLINK, please do not use pin 19 and 23 in hardware design.
Please contact engineer of MXCHIP if it is necessary to use the two pins.
(3) PIN21/24should be in high voltage or NC when power on, please aware it when designing circuit.
(4) If not used, please set the pin as NC, especially for CHIP_EN.
(5) Maximum I2C speed 400Kbps.
(6). Support PWM in hardware, maximum speed 2MHz.
(7). Please keep NC for unused pins.
