I wired it gnd, tx, Rx, 3.3v
Was I supposed to wire it differently as it doesn’t go on

I dont carry it, I ride it ahhahahaha

Many times tx goes to RX and RX goes to TX for UART pairs that’s said usually get some sort of light on so long as gnd and power/3.3V in this case is connected. The GND connection on the flipsky board side looks pretty lacking in solder but hard to say.

Yeah gnd does look like there isn’t any solder

On flipsky website it shows vin doesn’t go into 3.3v?
What does vin mean and we’re does it go?

Also @wafflejock on flipsky website they show vin going into 5v could that be an issue if my vesc doesn’t have one there

Yah “Vin” on pcbs just generically means “voltage in” but doesn’t tell you it it is 3.3V or 5V tolerant. Lots of integrated circuits (ICs) and microcontrollers (MCUs) will operate at one of those two voltages but sorry not sure with flipsky what it expects. The vesc should have GND and 5V by the PWM signal connection since receivers commonly use 5V, the regulator that supplied 5V to that pin can only deal with like 1A of current but should be plenty for the Bluetooth module (assuming it needs 5V)

Yeah tried with the other 5v and nothing
So I guess I need to solder the gnd and that is the issue

Thanks a lot

@wafflejock soldered the gnd a bit better and still nothing
No idea what the issue could be

Is there any chance that there is no led on this one?

Suppose it’s possible would have to take off the heatshrink and start probing around carefully with voltmeter or oscilloscope to say for sure. Had weird issue yesterday where one esc on my quadcopter kept getting into some reboot but worked sporadically, ended up replacing once I verified the signal going into it looks consistent.

Would love to see you riding it down the stairs (and back up if you survive)

Gnd- ground
Tx- transmit
Rx- receive
Vin- voltage in
Flipshite likes to do tx-tx and rx-rx for some reason. Try that

I am also considering making more battery build guides in this style for freeform (non-PCB based) batteries. Not sure if Im going to get around to it, as this was a lot of work, but maybe. Cus I agree, the battery builder thread is not a very digestible resource.

@Athrx @Halbj613
Note, that the pins are labeled VTX and VRX which could stand for VESC TX and VESC RX.
So wiring is in fact
GND - ground
VTX - TX
VRX - RX
VIN - 5V or 3V3

Ill check for VIN quickly

Which Flispky remote do you own?
VX1?

Yeah I know but nothing on the module lights up or shows that it is on

No idea why it’s not working
Guess I’m just having a unlucky day

Yeah
Just motors broke
Vesc broke (sort of)
Bt module broke

So depressign

@Halbj613
So it’s a BT module and not a remote receiver?

There seems to be no leds
Just open vesc tool app and proceed

What’s your vesc generation? 4 or 6?

First off, this will only work with android phones

Here’s the wiring:

Why didn’t you get the app yet? ^^ it’s as cheap as a McDonald’s burger
Just follow instructions and dont go the experimental dark way In the woods without a compass and a flashlight

Good luck!!!
