ML01S is a SMD hardware module based on nRF2401P from Nordic with on-board antenna and 1mW power,ultra-small size, suitable for applications of low power consumption.

Flight control(stable、high-speed、long range、low bit rate audio)megaphone, teaching audio,automatic match.

DTU is based on UART module and added with conversion circuit and power supply circuit of UART to RS-232/485. It has the same function with the UART module in data transmission,but the features and performance are different.DTU supports DC 8-28V wide power supply and power supply has good adaptability.Power supply and data interface are standard connector,which is easy to use. You can use it to realize the data transmission or upgrade wired UART devices.

AS69 is a UART module operating at 2.4GHz,supports up to 7 baud rates 1200-115200. Air speed automatically adapt to baud rate. In each baud rate, it supports full duplex transmission of unlimited packet length.

UART modules of AS32、AS62 series operate at 433MHz application free band, based on SX1278 and features FEC forward error correction，Max 64 bit continuous correction, strong diffraction and anti-interference and LoRa spread spectrum,with which the communication range is further.

UART modules of AS31、AS61 series operate at 433MHz application free and narrowband transmission, based on AX5043 from ON and features narrow spectrum occupancy,efficient error correction, strong anti-interference to ensure far communication range at higher wireless rate.
