HF-LPT100F & HF-LPT100S & HF-LPT100
Low Power Tiny WiFi Module Difference
Overview of Difference
LPT100F Support Maximum 5 Channel PWM output
LPT100S Support Maximum 4 Channel PWM output.
LPT100 Support Maximum 3 Channel PWM Output.
LPT100F Support Copper Line Antenna or IPEX conector Output.
LPT100S Support Copper Line Antenna Output.
LPT100 Support IPEX connector.
The Other Hardware and Software Feature of LPT100/LPT100S/LPT100F is the same. We
recommend to use LPT100F for design due to more IO control for SDK(Software Develop
Kit).

nReload Pin (Button) function：
1. When this pin is set to “low” during module boot up, the module will enter wireless
firmware and config upgrade mode. This mode is used for customer manufacture.
(See Appendix D to download software tools for customer batch configuration and
upgrade firmware during mass production)
2. After module is powered up, short press this button ( “Low” < 3s ) to make the
module go into “Smart Link “ config mode, waiting for APP to set password and
other information. (See Appendix D to download SmartLink APP)

3. After module is powered up, long press this button ( “Low” > 3s ) to make the
module recover to factory setting.
High-Flying strongly suggest customer fan out this pin to connector or button for
“Manufacture” and “ Smart Link” application.
nLink Pin (LED) function：
1. At wireless firmware and config upgrade mode , this LED used to indicate configure
and upgrade status.
2. At “Smart Link “config mode, this LED used to indicate APP to finish setting.
3. At normal mode, it’s Wi-Fi link status indicator
High-Flying strongly suggest customer fan out this pin to LED.

1.2.4. External Antenna
HF-LPT100 supports two way of external antenna as the following picture show, The I-PEX interface
or the PAD interface(remove the I-PEX connector). The user may choose one of them. If user select
external antenna, HF-LPT100 modules must be connected to the 2.4G antenna according to IEEE
802.11b/g/n standards.
The antenna parameters required as follows:
