The STD-601 is a miniature transceiver designed for industrial remote control and telemetry applications. The STD-601 has a simple serial interface and allows own communication protocol to be used. The RF Power, Data rate and Channel can be set through the use of dedicated serial commands.
The STD-601 434 MHz operates on the 434 MHz only and carries the CE marking and UKCA marking.

Evaluation Tools: TB-STD601
The test board TB-STD601 allows the STD-601 to be used in combination with Arduino MEGA 2560 to make simple switching and packet tests. An Arduino sample program* is included together with Windows setting interface to allow easy setup and control of the STD-601 module. As well as using the sample program, the user can develop own code to control the STD-601.
* Source code is available by email free of charge – visit the Documents page for details.
Features
- LCD screen
- 4 push buttons and 4 LEDs
- USB port
- 8 IO/Analogue Ports
- Receive / Transmit LEDs
- Packet Test Function
- Windows setting interface
- Arduino sample program (C++)
- TX/RX/ACK LED indicator

Adaptor Board: ADP-A-STD601, ADP-B-STD601
Each board, ADP-A-STD601 and ADP-B-STD601 contains CPU and dipswitches allowing the user to set the STD-601 parameters without any need to develop separate setting program. Parameters such as frequency band, RF power and bit rate can be set using the dipswitches.
When used in combination with the boards it allows user to easily setup communication by setting parameters using the dip switches and applying user data to the data in and out pins.
The adaptor board allows CDP-02 users to test the STD-601 using their existing CDP-TX-02E-R and CDP-RX-02E-R footprint and pin layouts. By allowing this compatibility, existing CDP users can evaluate the STD-601 quickly and easily without modifications.
Features
- Onboard dip switch to conveniently set STD-601 band, RF power, channel and bit rate
- No need to make setting program
- Convert STD-601 pin layout to CDP-TX-02E-R and CDP-RX-02E-R
- Board size matches those of CDP-TX-02E-R and CDP-RX-02E-R
- CDP module users can make communication test with STD-601 easily.
- Useable with STD-601 400 MHz and 434 MHz *
* Both boards include STD-601 400 MHz module. For STD-601 434 MHz module please specify when ordering.
