  • High precision Rigid聽PCB suppliers

Printed Circuit Board divided by character, there are rigid PCB, Flexible PCB, and rigid & flex PCB. Rigid PCB is a kind of electronic circuit relative cheap and used most frequently. It is widely used in consumer electronic products, electrical appliances, small appliances, telecommunications, automotive, medical equipment (such as mobile phones, phone, LED lighting, TV, DVD, computer products and peripherals, game consoles, chargers, adapters, remote control and other home appliances ...) ect.

Arduino UNO R3 Rigid Printed Circuit Boards MEGA328P ATMEGA16U2 with USB
 
 
 
 

Compared with the old version, R3 version has following changes:

 

1) Use Atmega 16U2 chip replacement 8U2 which means higher transmission rate and memory.
 

2) No need install driving program in the Mac and Linux system. (In the windows system requires an IDE drive)
 

3) increasing the SDA and SCL interface

 

.

Arduino UNO R3 is the latest easy-to-open-source controller, compared with the Arduino UNO and no major changes in hardware. The main difference is the USB-to-serial circuit, use ATMega16U2 microcontroller. No big change in softerware part.

 

Features:

 

1. Pin Changes:  add two I2C pins next to AREF pin (SDA and SCL, just  copy of Analog 4 and 5, not additional I2C interface). In addition, also added two pins next to RESET, one is IOREF that allows expansion board to adapt the onboard voltage, this pin just tell expansion board how much the current board voltage (such as UNO is 5V, the power supply pins can be seen as copy does not provide power to pull level on), and the other is the future stand place holder pin.

2. More stable RESET circuit. RESET key position has changed, was moved to the near corner of the USB interface board, more convenient.

3. ATmega16U2 replace 8U2, this does not mean there are 16K flash R3 make your code run faster. This update is for the USB interface chip. It allows UNO can simulate USB HID in theory, such as MIDI / Joystick / Keyboard.
