New Jumper T8 SG Lite?

Has anyone seen this? www.banggood.com/Jumper-T8SG-Lite-Multi-...itter-p-1338229.html

Price is interesting, and seems to be a great Devo 7e replacement for people who like smaller transmitters, but the pictures seem to show very low quality gimbals

Saw that one yesterday as well. Didn't notice the gimbals, but did notice that is only supports FrSky & S-FHSS protocols.
Also saw a Jumper T12 OpenTx version as well.

In the online manual (from the BG link) it mentions that supports all Deviation TX protocols, though... given that all Jumper Tx have built-in multimodule, seems weird to build a version with only the C2500 module. It would not be the first time BG has the wrong specs...

The manual says supports "many different protocols" not all Deviation protocols, and specifically says Frsky & S-FHSS. Price is very cheap.

Everything is kept to a minimum which i like.


Standard micro USB is included




First internal pictures.

The internal wiring is exactly what i would want from a modern transmitter. A main board as the central processing unit with all "add ons" being connected by simple ribbon cables that are removable, this is the perfect method for a Transmitter as it means that any future upgrades could be added by simply swapping components with the minimum of fuss.


The gimbals , the most important and by far the biggest query that anybody should have , trading the typical gimbal on a large mechanical cradle for a smaller more compact Gamepad style should have been adopted by manufacturers long ago. I understand that there are questions with regard to stick resolution but we should be now be able to create something that far surpasses the typical older style gimbal in both terms of resolution and reliability.


Gimbal resolution and range testing

What protocols does it support? Does it really have only a CC2500 module, as it looks from your picture?

Yes , there is no other module installed Available protocols are : Frsky, Frsky-V8, FrskyX,Skyartec,S-FHSS,Corona,PPM,USBHID.


I have literally just unsoldered an a7105 from a wltoys transmitter to see if theres a way to mod it into the radio

is there anyway to add more protocols to this say the bugs protocol or a syma protocol

This is what I am trying to find out, the RF board connector is a pretty standard 10 pin block so hopefully there will be a way. I have asked jumper for the pinout so hopefully they might oblige, otherwise I am sure the community will come up with something suitable.

So when attaching an A7105 is this the correct pin match ? ......

SCS to A14-TCK-PIN49
SCK to B13-SCK-PIN34
SDIO toB15-MOSI-PIN36
GPio- B14-MISO-PIN35--- Not needed
GND-GND
3V to 3V
