MicroRF Remote

If I use the 4 analog lines for soft servos an 8CH rx could work.

still need to look over the design a bit, can you find the vias I forgot to remove?

Replaced the advil caps with a couple electrolytic capacitors of the correct value...

It Works!

• Hooked to a single AA + 5V boost module
• 260 - 300 mah from the AA = about 10 Hours per cell
  • Oled at Full brighness
• Tx speed is up. 15Hz at idle (no conection)
• 70 Hz! Connected! (with no serial output.) did I count wrong in the code?

Will figure out a basic case and add Trim adjustments for the joysticks.

3/4 axis are off by +3...

Having multiple remotes should really speed up my other projects.

Now I can have more customized code on both rx/tx.

The new pcb was easy to solder in about 20 minutes, expecting it to just work I added the oled code and got the analog values displaying...but the wireless signal won't connect.

of course first I just had the wrong pin set on one...but the other... idk

Even without making a connection the speed is off. the only difference being the oled which updated only 2/3 times a second.

1. The nano remote is hitting about 15-16 hz.
2. The micro remote is hitting 8-9 hz.

Looking closer I think it could be a simple passive component. 

• The mcp1700 3.3v reg needs 2 1 uF capacitors. Micro Farad. (ran out of these)
• atmega328pu Oscillator needs 2 22 pF capacitors (tons of these...)
• I thought i was only off by a bit then I remember the advil caps were the wrong prefix.

I was off by 500,000x.

at least I hope this is the problem...because idk...

but to make it more strange rx board with the same caps seems to work fine with the test remote...

Other project rely on this one so I need it in a better working condition. its also 10000x easier to make multiples...

The nano-rf combo was supposed to make things easier..but they never really caught on and now their hard to find...

1. For the test remote A0/A1 had an interference problem. so its a working mess...
2. V1 has more parts:

• analog joysticks solder on directly 
• breakout the unused pins for trim/button/pot.
• I2c output for oled to have a menu/remote calibration.

I'll design a full case when I decide on the extra i/o bits. i think a switch and/or button will give enough options with the oled and the js switches also.
