Description

Product Description
Specification:
Origin: Mainland China
Type: for Arduino Series
Main controller chip: ATMMega328P
SRAM: 2KB
Operating voltage: 5V
Analogue input pins: A0-A5
Input Voltage:7-12V
EEPROM:1KB
Digital/O pins: 0-13 (6 support PWM)
Clock frequency:16MHZ
Memory:32KB
Function:
1. pin changes: in the AREF pin next to the addition of two I2C pins (SDA and SCL, just Analog4 and 5 copy, not an additional 12C interface)
In addition, in the RESET next to add two pins, one is IOREF, can let the expansion board practical on-board voltage, this pin is just to tell the expansion board the current on-board voltage is how many
(For example, UN0 is 5V, can be viewed as a copy of the power supply pin, and does not provide a flat pull-up) Another is a placeholder pin to be used later.
2. more stable REST circuit. RESET button location has also changed, was moved to the corner of the board near the USB interface, more convenient to press.
3. ATmega16U2 instead of 8U2, it doesn’t mean that R3 with 16k flash can make your code run faster.
This update is for the USB interface chip service, theoretically it allows UNO to emulate USB HID, such as MIDl/Joystick/Keyboard.
Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
