 Eason wireless module

Yl-800t wireless transceiver module

Chip solution :Semtech Sx1276/Sx1278 LoRa
carrier frequency :850 ~ 930MHz
Transmitting power : ≤ 100MW (20dbm) adjustable
Communication distance : open field visual distance 3-5km
Product size :34.2*18.4mm
communication interface :UART - TTL
Product introduction Yl-800t this is a Lora low-power wireless data transmission module that supports broadcast through transmission and half duplex communication in star protocol networking. The wireless communication part of the module is based on Lora spread spectrum modulation technology of Semtech sx1276 / sx1278, internal automatic spread spectrum calculation and preamble CRC error correction processing. It has ultra-high receiving sensitivity and strong anti-interference ability, and has a longer communication distance than other wireless data transmission schemes under the same transmission power, showing lower power consumption. The module uses stm8l low-power single-chip processor, so users do not need to carry out secondary development of the module. In the broadcast transparent transmission mode, the module does not change the user data and protocol, and sends is received;

Definition and description of pin:

Serial number name Pin definition
one GND The power supply ground is generally shared with the user's equipment
two VCC 2.1 ~ 3.6V (battery powered) or 4.5 ~ 5.5V
three EN Low level work, high level sleep These pins are all 3.3V level. If the user is a 5V MCU, it is recommended to do level conversion for stability, otherwise packet loss or high bit error rate will occur.
four RXD Data input, connected to user's TXD
five TXD Data output, connected to user's RXD
six AUX Communication status indication, which can be used to wake up the user equipment
seven SET Low level into fast channel, effective in center node mode
eight IO1 Reserved IO port for customized special functions These feet are unique to yl-800ts
nine IO2 Reserved IO port for customized special functions
10、11-14 GND Grounding
eleven ANT antenna

        The usage of EN pin in normal mode, central mode and node mode:

In normal mode and central mode, if the EN pin is set to high level, the MCU and RFIC of the module are deeply dormant, and the current is only 3.9ua. The module can not receive serial data and wireless data. Only when the EN pin is pulled down, the module can be awakened and restored to its original state. In the node mode, if the EN pin is high level, the module will be in the alternate state of sleep and CAD detection. The module can receive air data, but can not receive serial data. Only when the EN pin of the module is pulled down, can it receive the serial data.

      Note: if you want to configure the parameters of the module, no matter in which mode, the EN pin must be grounded before entering the command to configure the parameters.

      After the EN pin is pulled down for 50ms, the client can send data to the module from the serial port. The fast channel control pin is used to control the center module and node module to communicate quickly, so as to reduce the power consumption of the node module.

For example, when a central module communicates with a node module, their normal communication cycle is sent according to the sleep time. If the center module and the node module pull the set pin down when waking up, the module will remove the long lead for communication.

Note: when the set pin is dormant, it should be set high. If the customer does not need express channel, the set foot can be suspended in the air.
