05/07/2022 Equipment Autorisation Division Federal Communications Commission 7435 Oakland Mills Road Columbia, MD 21046 Subject: Class II permissive change Request FCC ID: 2A2HY-REFLECTORB5 To whom may concern:
Pursuant to CRF Section 2.1043, Reflect Innovation Ltd. requests a Class II permissive change to update the filing. All of the changes are not effect to the RF performance, function and power. Change list:
Granted on: 02/23/2022 1. Spring coating with tin. 2. Poron circle - We added a poron circle to the battery place. 3. Connector cable - we changed the length of the connector cable. 4. Light guide - we changing the texture of the plastic part. 5. eBOM - We removed and updated some components for various reasons:
i. Save BOM cost for unnecessary components that we used only for development ii. Improve current consumption iii. Replace unavailable components 6. Battery - We changed one approved battery with another approved battery. Both rely on standard 18650 cell. 7. Main PCB Layout - We did 3 layout changes on the Main PCB:
i. Changed battery connector to fit the new one ii. Made the hole in the middle of the PCB a bit bigger so the new batterys 8. Protection circuit will fit in it. i. Added test points for easier factory testing 9. LEDs PCB Layout - We did 2 layout changes on the LEDs PCB:
i. Rotated the 6 pin connector wires - The reason is that we wanted to be able to use COTS Molex wire with no need to invert its wires. ii. Added test points for easier factory testing. Main PCB layout Side A New Original Side B Electrical drawing of both sides New Original Wifi component & BLE component The RF Components are the same in both PCBs as seen below. Changed battery connector to fit the new battery The new connector p/n: B3B-PH-SM4-TB(LF)(SN). Connector header surface mount 3 position 0.049" (1.25mm) The old connector p/n: 53398-0367. Connector header surface mount 3 position 0.049" (1.25mm) Battery We changed one approved battery with another approved battery New Original Connector cable PICOBLADE 6 CIRCUIT 50MM, Molex p/n: 0151340600 Poron circle We added a poron circle to the battery place like the photo below. We added the Drawing file of the circle . The reason we did it is to make sure that the battery is held softly in its position. Its a standard solution for battery positioning. Light guide: We changed the texture of a plastic part We added the Manufacturer's report of the material - Reference 5 The Manufacturer's report has 2 options : 20% and 60% of RAL 9003. We are using the 20% RAL 9003. LEDs PCB layout: We did 2 layout changes on the LEDs PCB. We did 2 layout changes on the LEDs PCB:
i. Rotated the 6 pin connector wires - The reason is that we wanted to be able to use Commercial off-the-shelf Molex wire, and needed to rotate the connector to do so. ii. Added test points for easier factory testing Side A i. In red are the test points we added. Side B Spring coating with tin:
The circuit have 6 soldered springs that touches the electrodes that goes to the outer part of the device. The material that we used for both the old and new springs is the same Stainless steel
(also called SS316). On the final product we coated the springs so they will be soldered more easily to the board (Stainless steel rejected the tin with the old springs). Note that these are internal parts that the user doesnt touch or interact with. Sincerely, Signature:
