Notes:
1. These assemblies are ESD sensitive, observe ESD precautions.
2. These assemblies must be clean and free from flux and all contaminants. Use of no-clean flux is not acceptable.
3. These assemblies must comply with workmanship standards IPC-A-610 Class 2.
4. The ICs of the first build of these EVMs have a different marker.
5. Ref designators marked with an asterisk ('**') cannot be substituted. All other components can be substituted with equivalent MFG's components.
6. Install shunts on:
JP3 between CE and LOW (all)
JP4 between TS and FIX (all)
JP8 Install (all)
JP5 between D–/EN2 and Low (bq24250 only)
JP2 between D+/EN1 and Low (bq24250 only)
7. The first cycle of this EVM, the Top Marking of the IC is different from the latter cycles.
8. TFM252010A-1ROM from TDK inductor can be used.
