From component selection and reference design to module integration, SDK, firmware adaptation and reference-code support, we help customers evaluate and implement practical engineering solutions.

4G · 5G · NB-IoT · Wi-Fi
Module selection and alternate evaluation for industrial connectivity requirements.

GNSS · RTK · Timing
Evaluate positioning modules, timing requirements and antenna interfaces.

PA · LNA · RF Matching
Review PA, LNA and RF switch choices together with matching and filter constraints.

SDK · Firmware · Interface Integration
SDK and firmware integration, driver adaptation, interface debugging, demo verification and reference-code support for module implementation, with source-code examples where available.

SAW · BAW · EMI · ESD
Evaluate filtering, EMI and ESD paths before schematic and prototype validation.

ADC · DAC · Power IC
Compare ADC, DAC, regulator and power IC alternatives against circuit requirements.
Reference designs, code examples and alternative parts depend on availability and require validation against the schematic, PCB, firmware and prototype.
Sourcing for specified brands, MPNs and BOMs, with supply and international delivery coordination.
Chinese-brand component resources, candidate alternatives and project-specific assessment of parameters, package and interface compatibility.
BOM-Cost provides independent electronic component sourcing and BOM procurement support. We prioritize requested original parts and assess second-source options or alternatives when needed, with engineering support for selection and integration.
