DFRobot μHex - Low Power Controller

Pimoroni Ltd Verified independent store

→

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 could make it wo rk 60 days long. As it is using Atmega 328 Microcontroller, it has good general and powerful performance. It packs 14 GPIO and 7 power ports (4 of them could be controlled) which could suit most of your project requirements. Designed by maker Leo Yan. Note: Bootloader is write protected, please do not attempt to update Bootloader. For large load applications (such as motor controlling), please connect VCC & GND directly or supply with independent power. Features Hexagon design, compact size with 14 IO ports and 7 power ports 4 switchable power supply interfaces to reduce power consumption Two sleep-wake interfaces for convenient interactions with surrounding Designated Arduino development libraries Cross design in power and IO interfaces, directly supports 3 pin/4 pin sensor/actuator Large welding plate design 2.54 mm standard spacing plate 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 for 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 Solder Pad: 2mm／2.54mm Power in port: 1 Power out port: 6 (4 of them could be turn-off) Maximum Current: 2A Dimension: 28 x 31 x 2.3 (mm) Weight: 10g Documents Product WIKI Schematic Layout Arduino library Show more
