sparkfun / redboard

The RedBoard is SparkFun's take on the Arduino Uno. It combines the simplicity of the Uno's Optiboot bootloader (which is used in the Pro series), with the stability of the FTDI and a mini-B USB connector.

SparkFun RedBoard (DEV-13975)

The RedBoard combines the simplicity of the UNO's Optiboot bootloader (which is used in the Pro series), the stability of the FTDI (which we all missed after the Duemilanove was discontinued) and the R3 shield compatibility of the latest Arduino UNO R3.

The RedBoard can be programmed over a USB Mini-B cable using the Arduino IDE: Just plug in the board, select "Arduino UNO" from the board menu and you're ready to upload code.

redboard's Issues

Checklist design review for v22

1. We need to reconsider the resistor values on the LEDs. They are very bright. This has been a common complaint from EDU, and there are lots of comments on the product page about this being an issue.

2. Depending on what the DFM agrees to this Friday, I'm suggesting that we revert the silk to the previous style for the 10uF caps (C3, C6 and C13). I think the line for the positive side of a polarized cap will be confusing.

*I'll wait to finish BOM verification until we decide what to do here.

3. The mark on the STAT LED (13) is not ideal. I suggest we possibly revert these packages as well for this rev. Or we flip the LED 180 degrees.

4. should probably get the "v22 revised by: jim" in the sch and brd too. Also, the board is missing the other "based on:...." text objects.

5. Do we want to put a line over RESET pin silk? (it isn't really standard for us, but it is an active low pin, right?)

RedBoard Qwiic Double Check

*1) This is all still in a branch from the main Redboard. Any independent repo in github for the product might be appropriate.

1. Have you verified that the BOM in Sparkle is accurate (also checking for PROD_ID, NAME, VALUE, PREFIX)? [NO]
   comment: There is no current Redboard Qwiic in sparkle. The BOM does not match up with the current Blackboard in sparkle.

2. Are 0.1 inch headers lined up on 0.1 inch grid? [NO]
   comment: The SCL,SDA, AREF GND 9-13 pins Header is not aligned on a .1 inch grid and is not aligned with the other headers

3. Is the LED color standard followed? (red for power, blue for STAT, green for TX, yellow for RX) [NO]
   comment: The "ON" / Power LED is Green which is consistent with the Redboards but not our other products.

4. Are there fiducials on both the TOP and BOTTOM of the board? [NO]
   comment: Fiducials were only found on top layer

5. Is the CC/Design By included in tDocu? [NO]
   comment: Needs Designer and revisor names

6. Is 'Revised by:' and 'Revisor Name' included in tDocu? [NO]
   comment: Needs Names

7. Do all components have polarity or pin 1 labeled? [NO]
   comment: IC-14038 Needs Polarity labeled on silk
