## Description
|
||||
|
||||
**C Back Driver** is a steering gear drive board compatible with M5StickC. It adopts STM32F030F4P6 control scheme, uses I2C communication interface to communicate with M5StickC, and provides 4 sets of PWM steering gear drive interfaces (the drive power of the steering gear is directly connected to the M5StickC The internal battery can drive general specifications of the steering gear, such as: SG90, etc.). This module leads the I2C bus at the top of StickC and provides an additional GPIO interface through STM32 expansion. It can be used for general logic level and ADC analog signal input reading. With the LEGO compatible hole design on the back, users can easily integrate this driver board into the LEGO building block structure, which can be used to build controllable structures such as steering gear manipulators.

The **Timer Camera F** is a fisheye camera module based on ESP32-D0WDQ6-V3 with 8M PSRAM and 4M Flash on board. 3.0 megapixel camera (OV3660) with DFOV 120° and a maximum resolution of 2048x1536 photos can be captured. The camera features an ultra-low-power design, and the internal integrated RTC (BM8563) draws out the IRQ signal, which can be used for sleep and timer wake-up (sleep current down to 2μA). The built-in 270mAh battery provides more than one month of battery life with timed pictures (one per hour) enabled. The module supports WiFi image transfer and USB port debugging, and the HY2.0-4P output on the bottom can be used to expand other peripherals. The on-board LED status indicator and reset button facilitate program development and debugging. In terms of application, M5Stack provides a number of simple and efficient application development methods and interfaces for the TimerCAM series, making it easy for users to use and develop their applications. (including PC/Mobile photo shooting APP, cloud image HTTP interface for timer shooting, cloud AI recognition interface (not online yet), etc.)

## 描述
|
||||
|
||||
**C Back Driver**是一款兼容M5StickC的舵机驱动板，采用STM32F030F4P6控制方案，采用I2C通信接口与M5StickC进行通信, 提供4组PWM舵机驱动接口(舵机的驱动电源直连M5StickC的内部的电池，能够驱动一般规格的舵机,如:SG90等)。该模块对StickC顶部的I2C总线进行了引出，并通过STM32拓展额外提供一组GPIO接口。能够用于一般逻辑电平与ADC模拟信号输入读取。背部LEGO兼容孔设计，用户能够非常方便的将这个驱动板集成到LEGO积木结构中，可用于构建如舵机机械手等可控结构。
