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 work 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: [email protected]， [email protected] （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 2.3mm(1.10 x 1.22 x 0.09") * Weight: 10g Documents * WIKI (μHex - Low Power Controller) * Schematic * Layout * Arduino library Shipping List * μHex Low-power Controller x1 https://elecena.pl/product/22714202/hex-low-power-controller-discontinued 2023-03-06 https://elecena.pl/product/22714202/hex-low-power-controller-discontinued 2024-09-19
