New BlimpDuino board, now surface mount and RC compatible
Changes include:
- All surface mount technology, to make the board smaller, lighter and easier to manufacture.
- Now with 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)
The board is designed to fit in and work with both a modded toy RC blimp or a custom blimp gondola.
You can buy the board here.

- I've added all the links to the components. The only missing ones are the Sanyo LB1630 motor controllers. I've got a few but can't find the supplier right now. Anybody got a link?

- Thanks! I filed a RFQ and got back a few answers, at around $2.00 each. I suppose that will have to do for now, but in the production version we'll switch to a cheaper and smaller SMD motor driver.

- Do a search on the Sanyo LB1836M. I imagine in volume these should cost less than $1. They are a fairly direct replacement for the discontinued Fairchild FAN8200 which I've been using.
-
- I'm getting some LB1630M quotes that are now under $1. What's the main advantage of the LB1836M for you? I see it's aimed particularly at stepper motors, while we're just using small brushed motors. Does that make a difference?

- The LB1836M is a 2-channel (i.e. 2 motor) driver that handles up to 1A per channel. I believe it is pin-compatible with the Fairchild FAN8200 which I've been using with all of my robots (and blimp controller) for 2+ years, and it has a lower pin count than the LB1630M. I haven't tried the Sanyo part yet, as I managed to locate a surplus stash of FAN8200's, but once that supply is exhausted, I will switch to the LB1836M.

- Sounds good. And it's okay to use a motor driver chip designed for stepper motors for small brushed motors like ours? In other words we can ignore the "stepper" designation?
-
Comment by Howard Gordon on June 12, 2008 at 7:54am
- I've used the Fairchild "stepper" part with several thousand N20 motors, so I'd have to assume that is just a marketing designation.

Excellent. We'll get some and if they work well redo the board to replace the three 1630s with two of those. (Note to those following along--these chips are functionally identical. We're just optimizing the board for production efficiencies. Feel free to stick with the 1630s if you want)
In the meantime, I found a source for the 1630s (linked above), so the board component list is now complete.
