An FCC-photo reference showing a compact gateway mainboard with TYBT2 and TYWE3S radio modules, separate printed antennas, and accessible programming pads.
Project context
How this product is typically engineered
An FCC-photo reference showing a compact gateway mainboard with TYBT2 and TYWE3S radio modules, separate printed antennas, and accessible programming pads.
System architecture
Typical architecture
A typical implementation accepts 5 V USB power, regulates a shared low-voltage rail, uses Wi-Fi for LAN or cloud uplink, and exchanges local-device traffic through a second radio module over a board-level serial or GPIO link.
Engineering risks to resolve
Decisions to close before release
- Maintain dual-radio coexistence and antenna efficiency inside a compact plastic enclosure.
- Preserve local control and deterministic recovery when either radio or the upstream network fails.
- Protect device identity, credentials, debug access, and field-update integrity over the product lifetime.
Validation plan
Checks to define before production
- Measure 5 V input behavior, standby current, brownout recovery, and USB-port ESD immunity.
- Exercise Wi-Fi congestion, BLE multi-node traffic, router replacement, and long-duration online stability.
- Verify secure provisioning, credential erase, signed-update interruption, rollback, and production debug locking.
What to put in the RFQ
Files and records to agree before quoting
Use this list to agree the build inputs and release records for a similar product. The final set depends on the project.
Design baseline
Released schematic or block diagram, interface table, power states, critical constraints, and revision owner.
Manufacturing release
Gerber or ODB++, stack-up, centroid data, assembly drawings, approved DFM dispositions, and panel assumptions.
Material control
Released BOM revision, manufacturer part numbers, AVL or alternate rules, no-substitute lines, MSL handling, and exception approvals.
Validation record
Test method, acceptance criteria, sample or serial identity, measured result fields, and disposition. Example scope: Measure 5 V input behavior, standby current, brownout recovery, and USB-port ESD immunity.
Production release
First-article status plus the agreed SPI, AOI, X-ray, ICT, FCT, programming, rework, OQA, labeling, and packing records.
During RFQ review, we confirm the required fields, sampling, limits, approvals, and record-retention period. Confidential project information stays within the agreed access rules.
Development and production controls
Typical manufacturing scope
- Dual-radio gateway integration.
- Local-to-cloud protocol bridging.
- Programmable and testable modular hardware.
Technical image review
Board-level evidence
White-background views are published to make component placement, interfaces and assembly boundaries easier to inspect.
