Hi all,
Okay, I got the Adafruit amp in the mail last night. BTW this is what Thomas Benedini wrote back to me regarding hookup:
My Quiry:
Hi Thomas,
I would like to connect the Mini I just received from you to this Adafruit Amplifier:
https://www.adafruit.com/product/2130?gclid=EAIaIQobChMI6efijeu82gIVDlmGCh0FTwlUEAQYASABEgKdn_D_BwEIs it possible to connect it without the 220 ohm resistor and potentiometer? Just simply connecting the BEC 5v from the OP TCB to power it and the audio input (Speaker + & -) from the Mini directly to the A+ & A- on the amp?
I'm really cramped for space in my T55A RC tank, and I'm hoping just cables are needed to use this 2.5W amplifier.
Thank you for any help, Jerry
His response:
Hello Gerald,
this seems to be possible, by having a look only to the picture.
Having the schematic would be better.
No guarantee on any damages !!!!
I hope this helps.
Best regards
Thomas
So I hooked it up this morning, using a 4 ohm, 1 x 2 inch speaker (Mato sells them, as does Amazon). I think, not sure, they are rated at 3 watts. And all worked, volume is more in line with the other tanks, Taigen, HL, etc. Happy except the cannon sound for the T55A is a little disappointingly soft IMHO. I plugged a pair (total 4 ohm) speakers, rated 3 watts each, and it worked even better.
So great outcome, for $3.95 plus shipping.
Thanks, Jerry
