Power and ground rails and a voltage regulator, that's what. So I made a 'duino clone with features for Putting In Projects and called it PIPduino.
- Color-coded power and ground rails for each analog and digital pin,
- Dedicated I2C bus with 4 ports and pullups,
- Combo SPI / ISP connector,
- Serial/FTDI connector,
- Onboard voltage regulator, and
- Flexible power options.
Goodbye shields. Use low cost breakout boards instead.
|Before PIPduino (ick). And after (ah, much nicer).|
I did the same thing for my teensy board:ReplyDelete
Nice. Might be fun to clone a Teensy into the PIPduino form factor...Delete
Also, Micro Python on Teensy? Cool. Ibrahim got Micro Python running on the OpenMV Cam (STM32F407).
Where did you get the nice colored headers?Delete
I get 'em in bulk through Aliexpress.Delete
Nice! Except that I'd leave off the regulator. I like to keep the regulator external, that way I just need one for all the 5V devices. Simplifies things.ReplyDelete
But Ted, you *can* use an external regulator, just power the board from the 5V/GND pins. That's what I'm doing with it on the self-driving Jeep.Delete
Excellent method to harness the power of the 328... W/O all that shield crap.ReplyDelete
I've been doing mine on those small Veroboards from Thaishine or Tayda on Fleabay, Tayda is a little more generous but Thaishine is a US branch of Tayda and a little more expensive then Tayda ~ +10% But 3 to 4 day shipping via 1st class mail makes up for it,
