telemetry has uploaded  firmware, no need to upload firmware and modify parameter using it directly.

Feathers of 3DR Radio Telemetry Kit:

Adaptive control of HopeRF HM-TRP radio AT radio module based on open-source firmware configuration command for RT command and APM radio remote configuration when used together with SiLabs, Si1000 RF micro controller.

​Wifi Telemetry can be used for PIXHAWK or APM flight controller,it is same as 3DR radio telemetry.

Radio V5 Telemetry is new type, Either one can be used as ground or air terminal
