2.4 GHz RF Module RF2401 Series Modules: How to Distinguish?
By sdga:NiceRF Wireless Technology Co., Ltd
NiceRF: 2.4 GHz RF Modules RF2401 series modules are RF2401, RF2401F20, RF2401F27 and RF2401Pro.
How to distinguish 2.4 GHz RF Modules RF2401, RF2401F20, RF2401F27 and RF2401Pro:
What 2.4 GHz RF Modules RF2401, RF2401F20, RF2401F27 and RF2401Pro have in common:
1. Operating frequency: 2.4GHz
2. Operating temperature range: - 40 ~ + 85 ℃
3. Ultra low consumption shutdown mode
4. Internal integrated regulator
5. All four 2.4 GHz RF Modules support frequency hopping function
