XR1 Datasheet Pin No. Symbol I/O Type Function 17 ADC AI ADC pin (See the following Note 2.) 18 GND P Power supply reference ground pin Note: 1. P indicates power supply pins, I/O indicates input/output pins, and AI indicates analog input pins. 2. This pin can only function as an ADC input and not a common I/O. If this pin is not used, it must be disconnected. When this pin is used as an ADC input, the input voltage range is 0 V to 2.5 V. 2.

XR1 Datasheet parts. To prevent adverse impact on the antenna radiation performance, avoid copper or traces along the antenna area on the PCB. Ensure that there are no substrate media above or below the antenna and that copper is at a certain distance away from the antenna to maximize the antenna radiation performance. Figure 5-1 Antenna clearance part For details about the onboard PCB antenna area on XR1, see Figure 6-1.

XR1 Datasheet 6.3 Production Instructions 1. Use an SMT placement machine to mount the stamp hole module that Tuya produces onto the PCB within 24 hours after the module is unpacked and the firmware is burned. If not, vacuum pack the module again. Bake the module before mounting it onto the PCB. (1) SMT placement equipment i. Reflow soldering machine ii. Automated optical inspection (AOI) equipment iii. Nozzle with a 6 mm to 8 mm diameter (2) Baking equipment i. Cabinet oven ii.
XR1 Datasheet (2) If the 30% circle is pink, bake the module for 4 consecutive hours. (3) If the 30% and 40% circles are pink, bake the module for 6 consecutive hours. (4) If the 30%, 40%, and 50% circles are pink, bake the module for 12 consecutive hours. 4.

XR1 Datasheet Appendix: Statement Federal Communications Commission (FCC) Declaration of Conformity FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. This device complies with Part 15 of the FCC Rules.
XR1 Datasheet The firmware setting is not accessible by the end user. The host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.
