Product details
Description:
RELAY, as its namesake, is a M5Unit that implenments a Relay functions. Relay can be used as an electrically operated switch, uses an electromagnet to mechanically operate a switch,to where it is necessary to control a large power load circuit by a separate low-power signal, like a digital signal output from a mircoprocessor. Up to 30V DC and 220V AC.
There are 3 pins named: ON, OFF, COM. You can program to make COM connect to ON or OFF, just by high and low out put of a digital GPIO.
Description:
PRO TO?is a Unit size of universal prototyping board. You can have the total freedom to make your own project as you want it, with prototyping perboards that allows laying out customized circuit to interact with the M5 core GROVE Port.
Description:
EXT.IO?is a GPIO Expander. With simple I2C commands you can have up to 8 GPIOs.
Integrates PCA9554PW. This 8-bit I/O expander for the two-line bidirectionalbus (I2C) is designed for 2.3-V to 5.5-V VCC ?????? Open-Drain Active-Low Interrupt Output operation. It provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface.
IIC address: 0x27.
It?????s difficult to foresee the needs of your project from the start. EXT.IO is the perfect solution for expanding the number of IO. It allows you to add new features, logic,timing and sensing to alrady highly integrated designs.

Description:
RS485?is a TTL to RS485 convertor.
RS485 is a standard defining the electrical characteristics of drivers and receivers for use in serial communications systems, widely used in industrial field. multipoint systems are supported.
It is used to convert the TTL standard to the RS485 standard. If the outside serial device is RS485 standard, you can attach this unit onto M5stack, therefore, to implement the communication with RS485 device by TTL protocol.
Description:
DAC?is a unit can convert digital signal to analog signal like voltage waveform, audio waveform and so on. It integrates a 12-bit high resolution DAC chip named?MCP4725?which integrates a on-board non-volatile memory (EEPROM). The unit comunicates with M5Core with I2C. The DAC input and configuration data can be programmed to the EEPROM. I2C address is 0x60.

Description:
ADC?integrated with ADS1100 which is a fully differential, 16-bit, self-calibrating,del ta-sig ma A/D converter. It communicates through an I2C interface,which means you can collect AD data thru PortA on M5 core from this unit to enhence your A/D performance.
