F90A1-S is a UHF integrated reading and writing module based on PHYCHIPS PR9200 design. The maximum output power of the module can reach +25 dBm. With a 1dBi circularly polarized ceramic antenna, the reading distance can reach 2.5m, and can achieve more than 200tags/ s tag recognition rate, with stable multi-tag reading and anti-interference ability.
The F90A1-S integrated read-write module has been verified by a large number of tests and long-term uninterrupted work (180 consecutive days), and its stability and reliability can fully meet the needs of use.
| pins | Name | Description | Remarks |
| 1 | GND | GND | |
| 2 | P_EN | The power supply of the module is enabled. This pin defaults to a high level of 5V. When an external low level (0V) is connected, the F90A1 module enters a sleep state | |
| 3 | RXD | Serial interface reception, TTL level, low level is 0V, high level is 3.3V~5.0V | |
| 4 | TXD | Serial interface transmission, TTL level, low level is 0V, high level is 3.3V | |
| 5 | 5V | DC power supply, the input voltage is 5.0V, and the maximum working current of F90A1 is 500mA. | |
