All the necessary components for the new surface-mount BlimpDuino board
have arrived, so I spent a fiddly couple hours carefully soldering the tiny parts. (If you're going to solder SMD components, watch videos
on how to do it first).
The new SMD board is the smaller one on the right of the picture above, shown with the previous through-hole BlimpDuino board for comparison. As you can see, it's about 30% smaller. As noted in the earlier post, it has several significant improvements over the previous board, including:
- Two dedicated RC channel input ports, so you can easily fly in RC mode (for testing) or autonomous mode.
- A new power supply that can handle anything from 3V to 18v and output both 3.3v and 5v. This will allow you a range of battery options, from 2 or 4 AAAs (cheap) to a 7.4v Li-Po (expensive).
- Includes a port for a servo, for the vectoring thruster
- Includes ports for a Bluetooth wireless module and a magnetometer (compass)
Here's the bottom view of the two boards (new one is on the bottom):
