The first telegraph transmitter on the market, fully electrically and mechanically compatible with the Arduino Uno Rev 3!
For sale is a brand new kit for self-assembly by KRAIT Technologies, version for 80 meters only (designation: KT-004K/80), as shown in the pictures.
CWduino board allows to reach 500 mW of RF power when powered from 5VDC and 2000 mW when powered by 9VDC (e.g. from a 9V battery).
The frequency of the transmitter is fixed and adjusted with a trimmer. The system has an input for a telegraph key (straight or paddle). Integration with the Arduino Uno board allows you to easily build a semi-automatic telegraph key with an integrated transmitter. The system can also be used as an autonomous beacon. After adding another shield with a display and a keyboard, you can build a message memory or a decoder of transmitted characters.
The set includes two sample programs written in the Arduino environment.
Included:
- a set of components (SMT and THT components, cores, winding wire)
- professional double-sided PCB with a solder mask and a description layer
- SMA female angle connector
- goldpin sockets for integration with the Arduino Uno module
- the possibility of installing additional shields from the top
- printed assembly instructions
Note: The Arduino Uno board is not included in the kit.
