+# Module SERVO 2
+
+<el-tag effect="plain">SKU:M</el-tag>
+
+<div class="product_pic"><img src=""></div>
+
+##  Description
+
+**SERVO 2** is an updated servo driver module in the M5Stack stackable module series. It uses a PCA9685 16 channel PWM controller to control 16 channel servos at the same time. The power input is 6-12V DC and two SY8368AQQC chips are used for voltage reduction. 
+
+The maximum total power output of dual channel is 35W (5V / 3.5A * 2), and the maximum output power of single channel is 25W (5V / 5A). When the battery base is used for power supply, the maximum output power is 5V / 2A. The module communicates with the host directly through I2C (the default address is 0x40) however the I2C address can be changed through the dial switch. This also means that multiple Servo 2 modules can be stacked and used simultaneously. There is a power switch on the board to control the power supply of Servo 2.

+<div class="product_pic"><img src="assets/img/product_pics/unit/a_meter/ameter.webp"></div>
+
+## Description
+
+**A Meter Unit**  is a current meter that can monitor the current in real time. The 16-bit ADC (analog-to-digital) converter ADS1115 is used internally to communicate through I2C (0X48). In order to ensure the measurement accuracy, there is a built-in DC-DC isolated power supply, and the I2C interface is also electrically isolated through the low-power isolator CA-IS3020S. This prevents noise and surges on the data bus or other circuits from entering the local ground terminal to interfere or damage sensitive circuits. Each Unit is individually calibrated when leaving the factory, with an effective accuracy of ±1999 (3 digits after the decimal point) The unit has a maximum measurement current of ±4A, and an internal integrated 4A fuse to prevent excessive measurement current from burning out the circuit. Minimal Resolution reaches 0.15626mA.
+
+>? EEPROM (0x51) has built-in calibration parameters when leaving the factory. Please do not write to the EEPROM, otherwise the calibration data will be overwritten and the measurement results will be inaccurate.

+
+## Description
+
+**MIC Unit**  is a sound sensor with a built-in omni-directional electret microphone. The signal is amplified and output by microphone preamplifier max4466. The amplifier can effectively suppress power supply noise and common mode noise, and the output signal has high sound recovery and can be used in noisy environments. The unit can not only output analog signals, but also output digital level signals. The built-in LM393 double voltage comparator can set the comparison voltage threshold by adjusting 10K adjustable resistance. The sensor is very suitable for acoustic electrical conversion, audio recording / sampling, FFT acoustic feedback, voice switch and other projects..

+
+## 描述
+
+**COM.GPS** 是M5Stack堆叠模块系列中的一款，卫星定位模块.基于NEO-M8N模组开发，配备有源天线.NEO-M8N具备 -167 dBm 高接收灵敏度，并且保持系统低功耗.NEO-M8N 集成了 72 通道的 [u-blox](https://www.u-blox.com) M8 GNSS 引擎，支持多个 GNSS 系统：北斗, Galileo, GLONASS, GPS / QZSS，允许同时接收 3 个 GNSS 系统的数据.模组内部集成了可编程FLASH，可对固件进行升级。该模块具有较小的静态漂移，低功耗和紧凑的尺寸非常适合于车辆，PDA等手持设备，车辆监控，移动电话，相机和其他移动定位系统中的应用。M5Core与COM.GPS模块之间使用UART通信协议，通过模块内的拨码开关可设置UART通讯引脚.
+
+如果你想要更改串口波特率，请点击 ( [u-center-just-for-Windows](https://www.u-blox.com/en/product/u-center-windows) )查看.
+
+**注意: 为了使 GPS 模块获得良好信号，请在使用时将模块放置在室外.**
+
+**UART协议：波特率（默认为9600bps），数据位（8位），起始位（1位），停止位（1位），校验位（无）**
+
+?>COM GSM的RXD/TXD可以通过设置拨码开关接入的M5Stack的UART（TX(0/13/17)RX(5/15/16)），**M5Stack Fire** 中的 GPIO 16 / 17 默认与PSRAM连接，在使用GSM时会产生冲突，建议使用剩余两组中的任意一组UART引脚。
+
+?>右侧拨码开关无需设置。

+## 描述
+
+**A Meter Unit** 是一款电流计，可以对电流进行实时监测。内部采用16位ADC数模转换器ADS1115，通过I2C(0X48)进行通讯。为了保证测量精度，内置DC-DC隔离电源，同时I2C接口通过低功耗隔离器CA-IS3020S进行电气隔离，防止数据总线或其他电路上的噪声和浪涌进入本地接地端而干扰或损坏敏感电路。每个Unit在出厂时都单独进行校准，最小分辨率达到0.15626mA，有效值达到±1999（小数点后三位），最大测量电流为±4A，内部集成4A熔断器，防止测量电流过大烧毁电路。
+
+>? EEPROM(0x51)在出厂时内置了校准参数，请勿对EEPROM进行写操作，否则校准数据将被覆盖导致测量结果不准确。

+
+## 描述
+
+**V Meter Unit** 是一款电压传感器，可以对电压进行实时监测。内部采用16位ADC数模转换器ADS1115，通过I2C(0X49)进行通讯。为了保证测量精度，内置DC-DC隔离电源，同时I2C接口通过低功耗隔离器CA-IS3020S进行电气隔离，防止数据总线或其他电路上的噪声和浪涌进入本地接地端而干扰或损坏敏感电路。每个Unit在出厂时都单独进行校准，有效值达到±1999（小数点后3位），最大测量电压为±36V，最小分辨率达到0.490798455mV。
+
+>? EEPROM(0x53)在出厂时内置了校准参数，请勿对EEPROM进行写操作，否则校准数据将被覆盖导致测量结果不准确。
