Overview

Chip Solution: Semtech Sx1276/Sx1278 LoRa Carrier Frequency: 850~930MHz Transmission Power: ≤ 100mW (20dBm) Adjustable Communication Distance: Wide Field Sight 3-5km Product Size: 34.2 * 18.4mm Communication Interface: UART TTL Product Introduction: YL-800T This is a low-power LoRa wireless data transmission module that supports broadcast transparency and half duplex communication in star protocol networking. The wireless communication part of the module is based on the LoRa spread spectrum modulation technology of Semtech Sx1276/Sx1278, with internal automatic spread spectrum calculation and preamble CRC error correction processing. It has ultra-high receiving sensitivity and strong anti-interference ability, and can communicate farther than other wireless data transmission schemes at the same transmission power, exhibiting lower power consumption. The module adopts STM8L low-power microcontroller processor, and users do not need to perform secondary development on the module. In broadcast transparent mode, the module does not change user data and protocol, and what is sent is received;

YL-800T Dimensional Structure Diagram

Pin definition and description:

Serial Number	name	Pin definition
1	GND	Power ground, generally shared with user equipment
2	VCC	2.1~3.6V (battery powered) or 4.5~5.5V
3	EN	Low level operation, high level sleep	These pins are all at 3.3V level. If the user is a 5V MCU, it is recommended to perform level conversion for stability, otherwise packet loss or high bit error rate may occur.
4	RXD	Data input, connected to the user's TXD
5	TXD	Data output, connected to the user's RXD
6	AUX	Communication status indicator, which can be used to wake up user devices
7	SET	Low level entering fast channel, effective in center node mode
8	IO1	Reserved IO port for customizing special functions	These feet are unique to YL-800TS
9	IO2	Reserved IO port for customizing special functions
10. 11-14	GND	grounding
11	ANT	antenna
Usage of EN foot in normal mode, center mode, and node mode: If the EN pin is set to high level in normal mode and center mode, the MCU and RFID of the module will be in deep sleep mode, and the current will only be 3.9uA. The module cannot receive serial and wireless data. The module can only be awakened and restored to its original state when the EN pin is pulled down. If the EN pin is at a high level in node mode, the module is in a state of alternating sleep and CAD detection. The module can receive airborne data, but cannot receive serial data. It can only receive serial data when the EN pin of the module is pulled down. Note: If you want to configure the parameters of a module, regardless of the mode, the EN pin must be grounded before entering commands to configure the parameters. The EN pin needs to be pulled down for 50ms before the client can send data from the serial port to the module.The fast channel control pin is used to control the fast communication between the central module and the node module during communication, in order to reduce the power consumption of the node module. For example, a central module and a node module communicate, and their normal communication cycle is sent based on sleep time. If the central module and node module pull down the SET pin during wake-up, the module will communicate with the long preamble. Note: When the SET foot is in sleep mode, it should be raised. If the customer does not need a courier channel, the SET foot can be suspended in the air.
