Practical Application Scenarios
1. Miniature Handheld Industrial Remote Controller Matching EBYTE EID041 Sensor Modules
The ultra-compact 10*10mm size of E35-2G4T10SX perfectly fits narrow PCB space of portable industrial remotes. It transmits switch commands to EID041 temperature and humidity sensors via 2.4G transparent transmission. The ultra-low 1uA sleep current greatly extends button battery service life, and built-in data encryption prevents remote signal interception in factory workshop environments.
2. Wearable Medical Vital Sign Monitoring Nodes
Embedded into compact wearable medical sensors to upload heart rate and body temperature data to bedside gateways. 2.4GHz ISM band avoids interference with hospital medical equipment, stamp hole patch design enables SMT mass production, and multi transmission modes support one-to-many broadcast data upload for multi-patient monitoring systems.
3. Smart Home Small Appliance Wireless Control
Collocated with EBYTE RS485 to WiFi gateway modules to realize wireless control of small kitchen appliances and smart lighting. 540m open transmission distance covers single-family house space; point-to-point transmission mode ensures independent control signal without cross-interference between multiple home devices.
4. Mini Robot Car Wireless Data Link
Used as the wireless communication link between single-chip main controller and upper computer debugging terminal of miniature educational robot cars. Serial port online upgrade function supports remote firmware refresh without disassembly, small stamp hole size meets ultra-small robot PCB layout requirements.
5. Agricultural Portable Soil Data Collector
Paired with EBYTE soil moisture acquisition sensors to build battery-powered portable field collectors. Tiny module size reduces equipment overall volume, ultra-low sleep power consumption supports long-term field testing, and encryption transmission prevents agricultural sensor data leakage.
FAQ Section
1. Can E35-2G4T10SX communicate with other brands 2.4G modules directly?
No. This module adopts private transparent transmission protocol based on TLSR8208 chip. It can only communicate with the same model E35-2G4T10SX modules out of the box. Cross-brand 2.4G radio modules cannot establish normal data links without secondary firmware development.
2. What MCU voltage levels can match the UART port of this module?
The module uses standard 3.3V TTL UART electrical level. Direct connection with 5V MCU IO pins will cause permanent hardware burnout. Users need to add resistor voltage divider or level shifting circuits for 5V main control chips.
3. Does E35-2G4T10SX support custom encryption algorithms?
Yes, Ebyte technical team provides firmware customization service. Engineers can adjust built-in encryption rules or embed customer proprietary encryption algorithms according to project demands, with pre-sample verification before mass order.
4. Why is the actual transmission distance shorter than the marked 540 meters?
540 meters is tested under open line-of-sight environment without metal shielding or building barriers. Walls, metal cabinets, high-power electrical equipment will attenuate 2.4G radio signals and shorten effective communication range.
5. Can multiple E35-2G4T10SX modules work on the same site without signal collision?
Yes. Users can set independent device address codes to distinguish different radio nodes. Broadcast and fixed-point transmission modes are provided to isolate data streams between multiple modules and avoid data conflict.
