uServotino

Arduino project losing its mind

I'm using Ro-Bot-X's uservotino for my Venux robot. I recently had a problem where the sketch (program, for all you non-Arduino types) disappeared on me. The board would power up fine, but nothing would happen. Then I upload the sketch again and everthing is fine.

I thought it was an isolated incident, but it just happened again! Any thoughts on what would cause an Adruino to lose its mind?

Review: Ro-Bot-X uServotino

Introduction

Now, for the next in a series of reviews on Ro-Bot-X's boards. This one is on the beta version of the uServotino. It is an ATMEGA328 custom board with the Arduino bootloader pre-installed. 

The Kit

Ro-Bot-X's boards are usually available in three options.

Ro-Bot-X Board Reviews

 

Introduction

Recently, Ro-Bot-X send me three boards to evaluate. I had previously ordered his Robot Builder's Shield V1, and commented with some constructive feedback and a review on it after using the board for Penny.

µServotino robot controller

In November 2010 I have started the design of a new piece of hardware, the µServotino. Much like it's brother µBotino, this board is 2x2" in size (5x5cm), has a voltage regulator, switch, ISP connector, FTDI connector, 6 sensor connectors (GND, 5V, Signal) and 12 servo connectors (GND, Vin, Signal). There is also a UART connector (with associate 5V and GND pins) in case one wants to hook up a serial device to the robot. Plenty of filtering capacitors and 2 LEDs, one for power and the other for pin D13, that can be disabled by removing the J1 jumper.
