Hi Guys. I'm new here so go easy eh!
Inspired by THAT high altitude glider guy years ago Ive finally gone and designed a pcb.
I didn't bother posting before I got the pcb's as I'm sure there are heaps of people with many many great ideas that never become reality for one reason or another & I didn't want to add to the list!
The boards came back last week & with all the excitement I thought I would post on here & get ye guys to critique it!
The board is 10cm by 4cm. I guess I could have made it smaller but I wanted to space things out in case I need to rewire/cut etc. I think(?) it should be small enough for a glider
Its a 4 layer board with some nice gold flash.
Some of the components are from sparkfun; gyros & accelerometers. The rest are microchip & maxim stuff.
It has a PIC18F8720. Should have gone bigger but I have ten samples already & I've used it before & have a nice compiler for it & the microchip ICD.
2 Axis Gyro
3 Axis Accelerometer
Level shifter 3v/5v
Short range wireless, 10meters
Some ADC & DAC's
5 Servo O/Ps
I put an expandable SPI port so I can put some cheapo boards on with some extras. I got some SD card carriers in the mail so Ill put one on I recon.
I got the surface mount air-gun in the post yesterday so I'll start assembly tomorrow evening.
What do ye think?
I've tried to attach a picture but since this is my 1st post I don't know if it will come out ok.
I've gotten a two friends on board; one has the long range comms sorted & is a massive inspiration, the other is a good programmer. Should be fun!
