Order Information Base on customer detailed requirement, HF-A21 series modules provide different variants and physical type for detailed application. Figure 7. HF-A21 Order Information 1.3. Hardware Reference Design 1.3.1. Hardware Typical Application Figure 8. HF-A11 Hardware Typical Application Notes： nRST- Module hardware reset signal. Input. Logics “0” effective. There is 100K Ohm pull-up resister internal. When module power up or some issue happened, MCU need assert nRST signal “0” at least 300ms, then set” 1” to keep module fully reset.
HF-A21 Embedded WiFi Module User Manual Shanghai High-Flying Electronics Technology Co., Ltd www.hi-flying.com 12 nReady- Module boot up ready signal. Output. Logics “0” effective. There is 4.7K Ohm pull-up resister internal. The module will output “0” “or “Palmodic Signal” after normal boot up. This signal used to judge if module finish boot up and ready for application or working at normal mode. nLink- Module WIFI connection indication. Output. There is 4.7K Ohm pull-up resister internal. When module connect to AP (STA mode) or some WiFi STA connect to module (AP mode), the module will output “0”. This signal used to judge if module already at WiFi connection status. nReload- Module restore to factory default configuration.Input. Logics “0” effective. User can assert nReload signal “0” more than 3’s through button or MCU pin, then release, module will restore to factory default configuration and re-start boot up process. User need add 4.7K~10K Ohm pull-up resister external the module. If not use this function, then can use AT command AT+FRLDEN=off to disable it. UART_TXD/RXD- UART port data transmit and receive signal. 1.4. Typical Application Refer to HF-A21-SMT user manual for detailed application and module usage.

HF-A21 Embedded WiFi Module User Manual Shanghai High-Flying Electronics Technology Co., Ltd www.hi-flying.com - - Antenna Specification: Type: Chip Antenna Brand: High-FlyingGain: 2.0dBi 17 FCC INFORMATION (additional) OEM INTEGRATION INSTRUCTIONS: This device is intended only for OEM integrators under the following conditions: The module must be installed in the host equipment such that 20 cm is maintained between the antenna and users, and the transmitter module may not be co-located with any other transmitter or antenna. The module shall be only used with the internal antenna(s) that has been originally tested and certified with this module. As long as 3 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.). Validity of using the module certification: In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization for this module in combination with the host equipment is no longer considered valid and the FCC ID of the module cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. End product labeling: The final end product must be labeled in a visible area with the following: “Contains FCC ID: 2ACSVHF-A21”. Information that must be placed in the end user manual: The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user's manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual. Model: HF-A21
