Futaba FEP-02 Wireless Module

Manufacture: Futaba Corporation
Model: FEP-02
Features
Eight major features of FEP-02
- ARIB STD-T108 compliant, no license application required
- Multi-channel access prevents interference
- Easy to use with built-in communication protocol
- The 1mW type (FEP-02) operates at a low voltage and consumes low current, making it ideal for incorporating into remote controls and sensor devices.
- Interoperable with 20mW type (FEP-01)
- Communication distance is 300m (at 1.2kbps wireless speed)
- Equipped with a pattern antenna that is easy to incorporate
- Supports communication test functions that take maintenance into consideration when installing wireless systems

*1 This is the case when the directivity is consistent due to the pattern antenna. This value may vary depending on the surrounding environment and installation environment.
*2 A data modulation speed of 1.2 kbps has been added from production in January 2019. With this support, the technical standards conformity certification number for FEP-02 has been changed to “001-A11789.”
