E61 is a high-speed 433M wireless data transmission module developed by Chengdu Ebyte Electronic Technology Co., Ltd. It has built-in high-performance single-chip microcomputer and high-speed wireless RF chip, and UART serial port transparent transmission. 1W. The wireless module does not limit the length of the data packet in the "continuous transmission mode", and perfectly realizes continuous and uninterrupted transmission of serial baud rates such as 57600/38400/19200/9600; under the "fixed-length transmission mode", the user can configure the air rate , FEC enable, ciphertext and other parameters to transmit user data to the other party in the most efficient way at the currently configured air rate to achieve low latency/high response.
The high-speed transmission characteristics of the wireless module are suitable for polling sampling, handshake response communication, and support for the Modbus protocol. The underlying data transmitted by the wireless module in the air adopts Ebyte's unique encryption algorithm, and each packet of data is random, which makes the interception of data by other companies' wireless modules meaningless. The module also reserves 65,536 user-defined transmission passwords (cipher texts), and only the wireless module with a matching password can receive data to realize encrypted transmission of user data.
1. Product Features
Continuous transmission: The continuous transmission mode is not limited to the length of the data packet, which perfectly realizes the continuous and uninterrupted transmission of the serial port baud rate of 57600/38400/19200/9600/4800 and 2400/1200.
Fixed-length transmission: Users can configure parameters such as air rate, FEC enable, ciphertext, etc.; transmit user data to the other party in the most efficient way at the currently configured air rate, achieving low latency and high response.
User password: The module reserves 65536 user-defined transmission passwords (cipher text), only the wireless module with a matching password can receive data to realize encrypted transmission of user data.
High-speed transmission: 433M high-speed and low-latency, suitable for polling sampling, handshake response communication, and supports Modbus protocol.
Broadcast monitoring: Set the module address to 0xFFFF: it can monitor the data transmission of all modules on the same channel; the sent data can be received by modules with any address on the same channel, thus playing the role of broadcasting and monitoring.
Forward error correction: The module has software FEC forward error correction algorithm: it has high coding efficiency and strong error correction ability. In the case of sudden interference, it can actively correct the interfered data packets, greatly improving reliability and transmission distance. ; In the absence of FEC, such packets can only be dropped.
Sleep function: When the module is in sleep mode, that is, mode 3, the wireless receiver is turned off and the microcontroller is in a sleep state. At this time, the power consumption of the whole machine is about several uA.
Watchdog: The module has a built-in watchdog with precise time layout. Once an exception occurs, the module will restart within 0.107 seconds and can continue to work according to the previous parameter settings.
The module has four working modes, which are set by pins M0 and M1; the details are shown in the table below
