Iris Cube->ATMEGA328/168/88/48/8 development board compatible with 10+ chips

Compatible with ATMEGA (8, 48, 88, 168, 328) ( blank , P, A, PA, PB)-Ax chip, onboard USB to UART, 3.3V output, leads to ICSP and IIC interfaces

Warning: The BOM is automatically generated and may not match the actual situation. Please do not use the BOM table to place orders directly. Everything is subject to the PCB package and schematic values.

Please check out: Iris Cube->Series Microcontroller Development/Verification/Core Board Introduction

The silk screen on the physical picture is wrong and has been corrected in the PCB. If the schematic diagram does not match the number, description, etc. of the PCB, the PCB shall prevail.

--Xuexue drew Ah Nuo again, I'm not happy--

Regarding the four LEDs:

• P = POWER = power indicator/ +5V
• R = Rx = UART Rx LED/PD0
• T = Tx = UART Tx indicator/PD1
• L=L=D13 indicator/PB5

I like to use smaller resistors for LED current limiting, but although it can be seen clearly with the naked eye, it will be blurry when taking pictures. If necessary, please change the current limiting resistor to a larger value such as 10K.

For the trouble of identification during secondary use caused by multi-chip compatibility, an area is designed on the back of the circuit board to mark the chip and crystal oscillator information. Please use a marker or paint pen to write (the problem of difficulty in writing on the solder mask has been fixed):

Note : There are two jumpers on the board, please configure them as shown below:
