Botbitz TZ85

[PanoramicHarry]

After some of the brushed Botbitz 85A ESCs (at least two but one will do). Out of stock on both Botbitz and Ranglebox.

Be happy to reprogram a few if hobbyking has them in stock if you fancy?

So Hobbyking are all out of these as well.

I get the feeling they have been supersceeded by the AE- models

80 amp version:

65 amp version:

The descriptions say...

"The Turnigy AE series are based on new powerful microprocessor.
The new CPU means ultra fast sync timing, crisper throttle re..."

But cannot confirm this. Im after 2 TZ85a but may need to look to see if these 'newer?' models are programmable in the same way...

I hope they continue with tz85a else need someone to port SimonK to these pronto !

Has anybody cracked open the AE series ones to see what MCU it uses?

I can't imagine they'll discontinue the TZ85 with how popular it is. The site page is still up, I bet they're just waiting for another production run.

Im tempted to get the AE version just to open it up... as i could use it as brushless controller if else?

Challenge accepted. I am ordering one today. If all else fails, gives me an excuse to reuse the Red Brick controllers I have laying around make a fully brushless machine.

[Roboteernat]

snap, me too!

Speed controller arrived this morning, will attempt to hack and update later on.

UPDATE: And that appears to be a no. If there is a MCU around, it is either one I don't recognise or is there but the chip is on the underside of the red board, which is soldered on.

garh you beat me to it! yes it seems that ssome desoldering is required to program this board. i will be trying this later today and see what the controller is and do some electronics work to it, but currently, this is a no cannot be used at this stage.

As ocracoke states, the controller is soldered to the control board which is soldered upside down to the FET control board. Should be simple to unsolder so will update after lunch.

Otherwise i have one for a weapon assuming it is single direction - AE meaning Ariel vehicles - props only go one way!... then i can try use it for brushless drive - fwd and rev?

your choke (the black inductor square thing) on your PCB seems damaged - missing a corner, was that part of your unpacking? i would contact HK and say its broken...

[Ocracoke]

I did notice that but to be fair, it is only the casing, the actual device itself looks OK so I am not too worried.

If it comes to it, I'll make The Honey Badger 3.0 a fully brushless drive, I still have a pair of 100A Red Bricks laying around that would do the job as drive ESCs so no real worries here. Surprised though that the control unit is upside down here, seems a bit counter intuitive for cooling but then again, there was a thermal pad covering the entire green side of the ESC so....

I forgot to add that Hobbyking have said to me that the Turnigy TZ85A are not discontinued, but are being manufactured by factory and Hobbyking expect to be restocked in 4 - 6 weeks time....

Well, if you don't want the wait, the single channel FeatherTwos are a good alternative https://nutsandbots.co.uk/product/fe...ingle-channel/
