Product Description

[ Model ]: E31-TTL-500

[ Interface ]: UART

[ Power ]: 27dBm

[ Distance ]: 4000m

[ RF connector]: SMA-K

[ Frequency ]: 433MHz (425-450.5MHz)

[ Feature ]: E31-TTL-500 is a wireless transceiver module based on AX5043 of AXSEM (two-way transmission available). The module adopts FEC (forward error correction) algorithm, which greatly improve the anti-interference ability. E31-TTL-500 can be compatible with other Ebyte E31 series modules.
