Arduino Compatible Pro Mini (HCARDU0059 & HCARDU0081)

The Arduino Pro Mini is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, an on-board resonator, a reset button, and holes for mounting pin headers. A six pin header can be connected to an FTDI cable to provide USB power and communication to the board.

The Arduino Pro Mini is intended for semi-permanent installation in objects or exhibitions. The board comes without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires. The pin layout is compatible with the Arduino Mini.

We currently sell two versions of this board, a 5V/16MHz version (HCARDU0059) as pictured above, and a 3.3V/8MHz version (HCARDU0081).

Summary 5V Version
Microcontroller: ATmega328
Operating Voltage: 5V
Input Voltage: 5 - 12 V
Digital I/O Pins: 14 (of which 6 provide PWM output)
Analog Input Pins: 6
DC Current per I/O Pin: 40 mA
Flash Memory: 32 KB (of which 2 KB used by bootloader)
SRAM: 2 KB
EEPROM: 1 KB
Clock Speed: 16 MHz


Summary 3.3V Version
Microcontroller: ATmega328
Operating Voltage: 3.3V
Input Voltage: 5 - 9.6 V
Digital I/O Pins: 14 (of which 6 provide PWM output)
Analog Input Pins: 6
DC Current per I/O Pin: 40 mA
Flash Memory: 32 KB (of which 2 KB used by bootloader)
SRAM: 2 KB
EEPROM: 1 KB
Clock Speed: 8MHz

Please note that this diagram currently contains an error for the SPI interface. The alternate function for pin ADC4 is SDA not SCL. Thanks to oe1gca for pointing this out.

Hi there - can I just check that this is the right cable to program the pro mini?

I searched for FTDI cable (which I thought I need) on the site, but no result, but I came across this cable while browsing.

Yes it will work fine, it is the same as an FTDI cable, just in module form.

Perfect - in the basket it goes! Thanks for the quick reply. You know, you could probably upsell a little by either stocking an FTDI cable, or maybe a link to the module with "you might also want this" from the Pro Mini page. Or even just have the FDTI keyword in the module keywords so newbies like me could find it :)

Thanks for the suggestion. We recently switched to a new website and there are still many improvements to make. We will add the link to the Pro Mini today.

A fast flashing is normal for a pro min that has never been programmed and is actually a good sign as it means that it is running the bootloader and therefore the device is running. Could you describe how you are powering and programming the board? Can you also copy what error messages you are seeing.

The first one I opened worked fine .
Second 0ne come up with this error message .
Binary sketch size: 1,084 bytes (of a 30,720 byte maximum)
avrdude: stk500_getsync(): not in sync: resp=0x00 .
I was loading blink sketch the programmer is USB Serial Port Download Adapter
From you at the same time or and powered from it as well

The error message is just a generic error which just means that the Arduino IDE (avrdude) can't communicate with the device. This could be for any number of reasons. It is odd because it sounds like the device is running code, which leaves very little to go wrong with it. I would suggest checking the TX, RX and DTR connections from your programmer to the module and also check for any dry solder joints. Failing this, I would suggest contacting us at sales@hobbycomponents.com to arrange a return for testing.

Thank you for sorting out my pro mini. :D
