Our stock is the latest V2 edition. It has a revised front plate with clear plastic surrounds for the gimbal (a nice touch for those DIYers who wish to add LEDs). Internally there’s an MCU upgrade. It now uses the STM32F407ZGT6 which has double the flash memory of the previous MCU. There’s also an updated fan for improved cooling of the ELRS module.
The Jumper T20 V2 Gemini Radio Controller, is largely the same as the Jumper T20S radio, using the same design and uprated RDC90 gimbals, but with a more advanced internal ELRS module in comparison to the T20/T20S. The T20 Gemini utilises a dual frequency transmitter module which supports ELRS Gemini. Using Gemini Mode the radio broadcasts two separate transmit chains on slightly difference frequencies, simultaneously, to send control information to a Gemini compatible receiver twice. This helps to ensure even greater signal stability, as you effectively have two RC links. If one signal gets blocked then there’s a chance the other will still be received. To support Gemini mode, this T20 radio also comes with an omnidirectional, dual foldable antenna. This can be orientated so you benefit from using vertical and horizontal polarisation; helping to ensure optimal signal reception in various orientations and challenging environments for RF transmission, say urban areas. Since the radio requires more power to operate in Gemini mode and produces more heat, this version of the T20 now has a cooling fan attached to the heatsink on the back of the radio.
