E52-400NW30S vs E52-900NW30S — Full Parameter Comparison

 Section: Technical Resources / Component Selection

When choosing between the E52-400NW30S and E52-900NW30S, aside from the frequency band, almost all technical parameters are identical. Here's a detailed comparison table based on the datasheet:

 

 

 

Selection Guide:

• China & European markets: Choose the E52-400NW30S (433MHz band). This band has better diffraction capability, ideal for environments with many obstacles.
• North America & Asia-Pacific markets: Choose the E52-900NW30S (868/915MHz band), compliant with local ISM band regulations.
• Parameter tuning: For maximum range, set the air data rate to 7Kbps and lower the baud rate. For higher throughput, set the rate to 62.5Kbps, but range will drop to approximately 1.6km.
