Assuming they are fully operational, I'd be interested in at least a couple of the boards. I'm hoping to "standardize" on a power source using 18650 batteries for my portable audio projects and these boards look like great candidates. I'm not too concerned with CE/FCC as long as the boards aren't too noisy (EMI/RFI).

The 18650 board will pass testing no problem, it's just the all-in-one board that will have difficulty due to the minimally filtered high power amplifier output.
Anyway: good news: The power management and microcontroller part is confirmed to work: Used OptiLoader to burn a 8mhz bootloader and then a cheap USBasp to upload the program. Now that all individual parts of the PCB are confirmed to work: onto full assembly of both the all-in-one board as well as the 18650 board

Good news this close to Xmas is certainly positive! Looking forward to buying a few boards in 2018.
Merry Christmas to you Lutkeveld... |

Hi Lutkeveld I may be interested in these... can you tell me the main advantages that they may have over the C-amp.... (I know that the C-amp has solar controller and battery management but I'm interested in the amplifier itself) Thanks BJ

This one has on board DSP which means no external passive crossover and much more advanced functions like dynamic bass boost and psycho acoustic filters. It also has bluetooth.
The prototypes are working and I have been talking to board houses to get production rolling. Still no clear timeframe however. |

Looks fantastic. One question, how many channels of amplification? From the looks of it it could be 4 — if the tweeter and woofer share a common ground terminal on the speak/PWR header.

Great to see continued progress on this. Any RMS/peak limiting in the DSP? A link to full DSP features if possible would be great.

DSP options include:
- Up to 5 biquad filters per channel (LPF, HPF, BPF, notch, shelf etc) - psycho acoustic bass enhancement, - dynamic bass enhancement, - dynamic limiters - smoothclipping - channel mixing (left, right, stereo or mono)

If for nothing else, I want this board for the DSP capabilities only..! Any indication as to when it will be for sale?
