SV611 : 100mW Industrial Uart RF Module With Anti-Interference And ESD Protection
- SV611 is an Industrial class & highly-integrated RF module, TTL / 232 /485 can be chosen corresponding to SV611-TTL / SV611-232 / SV611-485. SV611 has good sensitivity and 100mW output power to achieve long RF range and reliable RF communication. To avoid the interference, SV611 provides 40 frequency channels and configurable Net ID. SV611 is flexible but easy to use, it comes with many parameters, such as: frequency, data rate, output power, Net ID, Node ID. Users can configure the parameters through PC or customer’s own device.
- SV611 strictly uses lead-free process for production and testing, and meets RoHS and Reach standards.
Note:
- High quality 3.3V LDO is integrated, and Pin CS / SET is 3.3V interface. TXD/RXD is also 3.3V for SV611-TTL.
- You can contact NiceRF to customize the version with sleep mode if you need low power consumption (Factory default version of this module does not support sleep mode).

| Pin No. | Definition | Description |
| 1 | VCC | Connected to the positive power supply (typical 5V) |
| 2 | GND | Connected to ground |
| 3 | TXD | TXD of the module and connect to external RXD |
| 4 | RXD | RXD of the module and connect to external TXD |
| 5 | SET | Configuration mode enable (low to enter into the setting mode, leave open or connect high level to exit setting mode) Valid when CS Pin is high or leave open. |
| 6 | CS/NC | For the default version of the module, this pin needs to be left floating (the module has a built-in anti-crash self-reset circuit) Note: Customers can customize the sleep version of the program (without self-reset function), low level sleep, current lower than 5uA, default high level output. |
