    This module can be used in IoT devices. The input voltage to the module should be nominally 3.3VDC and the ambient temperature of the module should not exceed 85℃. HF-LPT270 has one PCB antenna with max antenna gain 2.0dBi. If the antenna needs to be changed, the certification should be re-applied.
  • Page 19 9. Additional testing, Part 15 Subpart B disclaimer The final host / module combination need to be evaluated against the FCC Part 15B criteria for unintentional radiators in order to be properly authorized for operation as a Part 15 digital device. The host integrator installing this module into their product must ensure that the final composite product complies with the FCC requirements by a technical assessment or evaluation to the FCC rules, including the transmitter operation and should refer to guidance in KDB 996369.
