DFR0343 数据手册
    UHex Low‐power Controller SKU: DFR0343   μHex Contents      1 Introduction 2 Specification 3 Pin Definition 4 Programming 5 Sample Code 5.1 Low power Consumption Application 5.1.1 -Wake up by Interrupt 5.1.2 -Wake up by Timer 5.1.3 -Integrated Application 5.2 General Application Introduction μHex is the first low-power controller which is compatible with Arduino. It is very suitable for the battery power supply environment. A 210mAh CR2032 cell battery can support it standing by 60 days with using PIR sensor (SEN0171) as a trigger. As it is using Atmega 328 Microcontroller, it has good general and powerful performance. It has 14 GPIO and 7 power ports (4 of them could be controlled) which could meet most of your project. NOTE 1. Please don't update the bootloader since it is different from the Arduino Pro or Pro Mini one. 2. Please connect an external power supply, if you want to make some large curre nt application such as servo control. Specification                  Microcontroller: ATmega328P (board type: Arduino Pro or Pro Mini (3.3V, 8 MHz) w/ ATmega328 ) Operating Voltage: 2.7 - 5V Clock Frequency: 8MHz (RC) Sleep Current: 0.12uA@3V3, 0.16uA@5V (watchdog OFF) Flash: 32 KB ( 0.5KB used by bootloader) SRAM: 2 KB EEPROM: 1 KB Digital I/O Pins: 14 (PWM: 3,5,9,10,11) Analog I/O Pins: 6 UART Interface: 1 I2C Interface: 1 Interrupt interface: 2 Power in Port: 1 Power out Port: 6 (4 of them are controllable power port) Maximum Current from Controllable Power out: 2A Dimension: 28 x 31 x 2.3 (mm) Weight: 10g Pin Definition uHex Silkscreen Digital Interface RX 0 PWM Interface Analog Interface Proprietary Function Serial TX 1 2 2 3 3 3 INT1 5 5 5   9 9 9   10 10 10   11 11 11   A0 A0 A0 A1 A1 A1 A2 A2 A2 A3 A3 A3 SDA SDA A4 INT0 I2C SCL SCL A5 DTR + DTR VCC   ⊕ GND     Controllable power port Programming The board type of uHex is same to Arduino Pro or Pro Mini (3.3V, 8 MHz) w/ ATmega328, you could select it in the board menu, and program it with FTDI programmer. (Note: The bootloader of uHex is different from Arduino Pro or Pro Mini one. Please don't update bootloader by this one.) uHex_FTDI_connection_diagram Sample Code Low power Consumption Application Please download the Arduino library microPoly Library first. https://github.com/LeoYan/ArduinoLib/tree/master/microPoly -Wake up by Interrupt   Code: pinTrigger.ino Function: The uHex is in sleep state until pin2=LOW and pin3=HIGH. Once waked, the LED on the board will flash for some seconds and then go to sleep again. -Wake up by Timer   Code: timerTrigger.ino Function:The uHex is waked by period timer (using watchdog timer). Once waked, the LED on the board will flash for some seconds and then go to sleep again. -Integrated Application   Code: measure.ino Function: 1. The uHex is in sleep state until Timer is overtime or Button is pressed 2. The uHex sample data every 1 minute. If button is pressed the average data will be display on the LCD screen. After some seconds, it will go to sleep again. General Application In the scope of uHex ports, the program from Arduino UNO/Pro Mini can be run on the uHex. Powered By DFRobot © 2008-2017
