700 vs 800 series circuit board differences

Postby polypmaster » July 24th, 2017, 8:06 pm

Does anyone know what the actual differences between the 770 circuit board and the 870 circuit board are? I'm looking to replace my 870 board and visually I can't tell the difference between the two. The 770 seems to be a bit cheaper, but I can't tell if it is actually any different.

I have 2 870 PCAs without a home.

One is from my 880, 2013 firmware. The 880 UI board stays with the 880. I repaired a 870 main board which was missing power to the UI board and PWM signal to the cliff sensors. It is now in my 880 which runs 2X a week to see how long it will last, 2013 firmware. The other came from an eBay auction with a charging error 5. Re flowed solder on Q17, 2015 firmware, I don't trust it yet, haven't had it in a 800 chassis for complete checkout. All bits pass in 500 chassis with bin, rear cliffs and bin sensors remotely connected. In US?

I'd also be willing to trade the 870 board I have if you think it is worth anything.
