FPV 433Mhz Radio Telemetry Kit 100mW

This radio telemetry system is designed as an open source Xbee replacement radio set, offering a lower price, longer range (approx one mile) and superior performance to Xbee radios. It’s available in 915Mhz and 433Mhz; and in the following configurations:  serial board (for the air) and USB (for the ground).

The system provides a full-duplex link using HopeRF's HM-TRP modules running custom, open source firmware. Interface to the module is via standard 5V-tolerant TTL serial / FT232 USB serial.

The SiK firmware includes a bootloader that permits radio firmware upgrades over the serial interface, and radio firmware with configurable parameters. Firmware upgrades and configuration are fully supported in the APM Mission Planner. Configuration is also possible through the 3DR Radio configurator and AT commands.

Features:
• Very small size
• Light weight (under 4 grams without antenna)
• Receiver sensitivity to -121 dBm
• Transmit power up to 20dBm (100mW)
• Transparent serial link
• Air data rates up to 250kbps
• Range of approx 1 mile
• MAVLink protocol framing and status reporting
• Frequency hopping spread spectrum (FHSS)
• Adaptive time division multiplexing (TDM)
• Support for LBT and AFA
• Configurable duty cycle
• Built in error correcting code (can correct up to 25% data bit errors)
• Demonstrated range of several kilometers with a small omni antenna
• Can be used with a bi-directional amplifier for even more range
• Open source firmware
• AT commands for radio configuration
• RT commands for remote radio configuration
• Adaptive flow control when used with APM
• Based on the HopeRF HM-TRP radio module, featuring an SiLabs Si1000 RF microcontroller

Specs:
'Air' and 'ground' variants, FT232-style pinout and USB connector, respectively
RP-SMA connector
Maximum output power of 100mW (20dBm), adjustable between 1-20dBm
-117dBm sensitivity
Standard TTL UART interface
Data transmit and connection status LED indicators
Dimensions (USB board for ground): 55x17mm
Dimensions (Serial board for air): 46x20mm
Weight (USB board for ground): 7.5g
Weight (Serial board for air): 5.6g

Is the cable available separately?

Fully working now! Just have to adjust the frequency! I sell my 433Mhz or trade for a 915Mhz, since this is the correct frequency.

Any one helps to chose a cheap way to mesure battery voltage using this and a crius AIOP V2?

I have just put it to work, and i verify that im having troubles with gps locking... im near a window, and i have a solid fast gps lock, but if i have the telemetry on, it just wont always lock, and the position/orientation, just keeps changing... it seems that its somehow interfering with gps signal, or gps itself. I read that if i go outdoors the problem decreases, i have not tried to fly it in this condition... Anyone experiencing similar situation?

Hi, I am trying to build a multicopter and I already have an Arduino megapirate kit. Could I use this telemetry kit as an RX-TX to control the multicopter using the computer and a joystick? thank you very much for your replies

Plug and play setup with apm2.5. The range is only a few hundred feet, not nearly as far as 900mhz version out of the box. I think it needs a different antenna. Overall good buy works well.

Struggled to get these to work with Mission planner at first, then realized they must connect at 57600, the APM's USB connection must also be unplugged. Updated and everything seems to work fine, I have not done a range check yet.

I did order this 433 telemetry as a spare part. Now my existing telemetry with APM2.5 is broken, so I did decided to use this HK 433 telemetry between APM2.5 and MissionPlanner, as with previous one. It worked only one time, with power = 11 as from stock. The range was really very short, like 25m. Then I decided to increase power to 20 and I did update firmware using firmware update from Mission Planer. Update was "Success", but now it try to connect (green led is continue), but not able to connect with APM, it stops ar 30pcnt. Do you guy have a good experience with this telemetry? Any tips how to make it working?
