Detailed Description

Arduino PRO MINI AVR Core Development Board with
Headers & Installed Bootloader
Arduino ProMini Clone with headers & Wider Voltage Range. Get the same power as the UNO, or Nano in a low cost and small footprint. Features a Atmega328, 8bit, 16mHz processor, built in 5V regulator, 8 analog inputs and up to 14 digital I/O pins. This module does not have a USB connector. There are 5 dedicated 100 mil spaced pads for connecting the FTDI cable (DTR,TXO,RXI,VCC,GND) or a USB/TTLconverter module. The ProMini is ideal for use after you have perfected your idea on a Nano or Uno and want to embed it in the final project. Intended for advanced users. 1st. time Users should take advantage of the Arduino Nano to gain skills. Information & Freeware available through www. arduino.cc.en and others on-line.
The pre loaded Bootloader, allows Programming with an (off board) USB to TTL converter (our Stock # 31573) or a FTDI smart cable
Features:
Processor: 16 MHz ATmega328
Power: 3.3-12VDC On-Board Regulator (Operating 5 VDC)
Note: for 3.3-5V input Use the Vcc Pin
for 5.5-12V input Use the RAW pin NOT BOTH
Digital I/O : 14 (with PWM available on 6)
Analog Input: 8
Memory: Flash: 32K (-2K for bootloader)
SRAM: 2K

	Great price, but doesnt work from 12V supply
Bought 4 of these. Great price. Bootloader worked fine on all 4. But the voltage regulator is not the LG50 as shown in the schematic. LG50 is the marking found on the Micrel - now Microchip - MC5219-5.0 regulator. The MC5219 chip can take 12V input, 20V absolute maximum. But the regulator on these boards is marked 4BMD and burns out at around 10 or 11V on the RAW pin. But the boards worked perfectly below 10V. So these Arduino Pro Mini boards are an excellent deal if your project doesnt require higher supply voltages.

	A friend and I bought both pro minis 3.3 and 5v and the programmer
My friend and I bought 31355mp arduino pro mini 5vdc w/berg pins, 31811mp arduino pro mini 3.3vdc with no berg pins and the 31573 USB to serial TTL 5 and 3.3 programmer. 3 stars on one and 5 stars on the other and they are pretty much the same thing. The person that had the 31811mp and the 31573 programmer 3 stars. Only problem we had was flipping TX/RX duh on our part. If DTR was a problem for you, hold the reset and let it go after the compiler is done before the programmer AVRdude runs. All worked great. It took time but most was wiring on our part. If you have an after market USB to serial no DTR, do as mentioned above, hold reset, let go when you see AVRdude launch. Applies to GCB Great Cow Basic and Arduino IDE, etc.

	Does not seem to have boot loader
I have been trying to load a sketch to this and kept getting errors on upload. Finally found diagnostic where board is supposed to flash LED connected to pin 13 when reset switch is pressed. It does not. This seems to indicate no boot loader installed. Using the MPJA 31573MP interface to upload. IDE finds port and begin begins sending data but stops and errors every time.
