|
||||
|
||||
### General Description
|
||||
M5Stack recently launched the new AIOT(AI+IOT) Camera powered by Kendryte K210 -an edge computing system-on-chip(SoC) with dual-core 64bit RISC-V CPU and state-of-art neural network processor.
|
||||
<br><br>
|
||||
M5stick-V AI Camera features its integration with machine vision capabilities, featuring the unprocessed acceptability to AI Visioning with high energy efficiency and low cost. We co-oped with Sipeed providing the MicroPython environment makes programming onM5stick-V easier.
|
||||
<br><br>
|
||||
The module comes with the OmniVision OV7740 sensor, using the OmniPixel®3-HS technology, providing a best-in-class low light sensitivity, making it ideal for machine vision.

## Description
|
||||
|
||||
ADC_HAT is another type of C-HAT specifically design for M5StickC controller. Same as ADC unit, this is an ADC converter component for stickc. Packed with an ADC converter chip ADS1100, which is a fully differential, 16-bit, self-calibrating, delta-sigma A/D converter. Extremely easy to design with and configure, the ADS1100 allows you to obtain precise measurements with a minimum of effort.
|
||||
<br>
|
||||
The ADS1100 consists of a delta-sigma A/D converter core with adjustable gain, a clock generator, and an I2C interface.
|
||||
<br>
|
||||
ADS1100 itself is able to accept a differential input from -5 ~ +5 V, but we have limited the input to 0~12V by adding on the peripheral circuit design of this IC.

## Description
|
||||
|
||||
**RS485-HAT** is a TTL to RS485 converter for M5StickC. Among M5stack products we have 5 items that include TTL to RS485, they are RS485 unit, RS485 HAT, PLC, LAN, BASE26 they have different input voltage, vary from 5V - 12V.
|
||||
<br><br>
|
||||
In this RS485-HAT, it consists of a 485 automatic transceiver circuit and a DC-DC buck circuit which can drop an input 12V to 5V.
|
||||
<br><br>
|
||||
RS485 is a standard defining the electrical characteristics of drivers and receivers for use in serial communications systems, widely used in the industrial field. multipoint systems are supported.
|
||||
<br><br>
|
||||
It is used to convert the TTL standard to the RS485 standard. If the outside serial device is RS485 standard, you can attach this hat on top of stickc, therefore, to implement the communication with RS485 device by TTL protocol.

|

## Description
|
||||
|
||||
This is one of the communication devices among M5Units, a non-modulation Laser receiver. It is mainly built with a laser transistor.
|
||||
<br><br>
|
||||
Laser communications devices are wireless connections through the atmosphere. They work similarly to fiber-optic links, except the beam is transmitted through free space. While the transmitter and receiver must require line-of-sight conditions, they have the benefit of eliminating the need for broadcast rights and buried cables. Laser communications systems can be easily deployed since they are inexpensive, small, low power and do not require any radio interference studies.
|
||||
Two parallel beams are needed, one for transmission and one for reception. Therefore we have a LASER.TX parallelly.
|
||||
<br><br>
|
||||
Port type of this unit is PORTB.

||||
laser signals. In order to get the result of this demo, you will need to connect LASER.TX
|
||||
and LASER.RX with PORTC(blue) respectively onto two different M5Cores with M5GO bases on
|
||||
bottom. Then flash the demo into both M5Core device.
|
||||
When testing the demo, you need to point the TX unit to RX, and press the button TX connected
|
||||
device. RX connected device will reponse with a display,and will show what is received .

## Description
|
||||
|
||||
**MINI_PROTO** is an M5Unit size of universal prototyping board. Smaller than the PROTO unit, the size is exactly the same as the regular M5unit. You can have the total freedom to make your own project as you want it, with prototyping boards that allow laying out the customized circuit to interact with the M5 core CONNEXT Port A, B or C.
|
||||
<br><br>
|
||||
For different CONNEXT ports, you will be able to interact with different pins that ported out from ESP32.
|
||||
<br>
|
||||
- PORTA: GPIO 21, 22
|
||||
- PORTB: GPIO 36, 26
|
||||
- PORTC: GPIO 16, 17

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.
|
||||
|
||||
used for converting TTL level to RS485 level. If the device to be controlled only can communicate with other device through RS485, you can connect this device with M5Core through this unit. In this case, you could easily control a RS485 device with [UIFlow](http://flow.m5stack.com).
|
||||
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.
