Practical Application Scenarios
1. Embedded Engineer LoRa RF Performance Pre-Testing
Hardware R&D engineers use this E220-400MBL-01 kit to quickly test the transmission distance, receiving sensitivity and air rate parameters of E220 LoRa modules before mass hardware design. Connect the board to laptop via Micro USB without extra MCU wiring, adjust onboard buttons to send test packets, record real RF data to confirm if LLCC68 LoRa chip performance matches agricultural sensor project requirements.
2. University Electronic Lab IoT Teaching Platform
Electronics colleges adopt this evaluation board as teaching hardware for wireless IoT courses. Students master LoRa transparent transmission, wake-up and encryption functions through USB serial debugging, and replace pin-compatible E30/E32 modules on the same board to compare different Sub-GHz chip signal differences in experimental courses.
3. OEM Firmware Secondary Development Verification
OEM device developers build custom Modbus wireless collection logic based on the onboard STM8L151G4 MCU of the test kit. Complete end-node firmware debugging offline, and verify data interaction with E870-S LoRaWAN gateway before mass production of soil moisture sensor terminals, avoiding costly prototype PCB rework.
4. Hardware Maker Rapid Prototype Validation
Industrial hardware makers use the breakout pin header to directly wire external EID041 temperature and humidity sensors to the evaluation board. Rapidly build temporary LoRa data acquisition prototypes without designing custom carrier boards, and test signal stability inside factory workshops before formal product layout.
5. After-sales Technical Fault Diagnosis Tool
Ebyte technical support teams carry this portable USB test board to customer sites. Plug in the customer’s faulty LoRa module to judge RF receiving failure, serial communication abnormality or power supply defects quickly, greatly shortening on-site LoRa equipment troubleshooting time for smart meter and irrigation projects.
FAQ Section
1. Can I swap other Ebyte LoRa modules on this E220-400MBL-01 board?
Yes, the carrier board reserves unified pin definitions for E07, E30, E220, E32 and E22 series SMD LoRa modules with the same stamp hole package. Users can replace different frequency or power versions of LoRa chips without modifying wiring or software code.
2. Do extra driver software need to be installed to connect the kit to PC via USB?
No extra third-party drivers are required for mainstream Windows, Mac and Linux systems. The onboard USB to TTL circuit is recognized automatically after plugging in, and standard serial debugging tools can directly read and send LoRa test data.
3. Can the onboard STM8L151G4 MCU be rewritten with user custom firmware?
The STM8 master chip on the evaluation board is open for secondary development. Ebyte provides full GPIO and LoRa communication source code for free, engineers can rewrite custom transmission logic, sensor data acquisition and Modbus parsing programs directly on the board.
4. What accessories are included in the official full set of E220-400MBL-01 kit?
The complete package includes the pre-soldered E220 test board, 433MHz 4dBi rubber antenna and Micro USB power data cable, all necessary hardware for immediate out-of-box LoRa testing without extra purchases.
5. Does this evaluation board support long-distance outdoor field signal testing?
It supports outdoor range testing with matched antenna. But users need to prepare portable mobile power for field use, as the kit only obtains power through computer USB ports without built-in rechargeable batteries.
