1. Milling PCBs + Xbee replacement
@kennethlimcp

2. Milling PCBs
Basics + usefulness + issues

3. How it works
• Milling Concept
• FR4 Copper board
• High-speed
spindle
• GERBER files

4. Usefulness
• Rapid circuit
prototyping
• Minimal cost
• Easy to setup and
use
• 2 layer achievable

5. Common issues
• Blunt cutter
• high wastage
• “extra” copper plane
• Supervision required
• manual via linkage

6. Voltera

7. Xbee replacement
What + Why + Challenges

8. JN5168 from NXP

9. Why
• MCU + RF transceiver in 1
• Small form factor
• FCC-Certified
• Low cost
• Supports various protocol
(Zigbee, 6LowPan…)

10. Similar Concept
• bluz.io
• Using Nordic
nrf51422 module
• Basically a
breakout board
+ friendly form
factor

11. Challenges
• Documentation is
everywhere
• Have to “reverse-engineer”
• Bootloader not open source
• Need to use proprietary
software
• own footprint
