IoT endpoints and wearables push the limits of battery life, PCB area, and wireless performance in devices that must operate for months or years on a single charge. Restar Electronics supports IoT OEMs with 500,000+ in-stock SKUs, 24-hour RFQ response, BOM matching, quality inspection, and global shipping for tracker, wearable, and LPWAN node programs.
Miniaturized Components for Connected Edge Devices
Asset trackers, pet collars, and logistics tags combine GNSS, LTE-M/NB-IoT, or LoRa radios with ultra-low-quiescent power management on coin-cell or thin-film battery budgets. Restar stocks compact passives, low-power LDOs, and antenna components optimized for space-constrained IoT PCBs.
Health wearables add bio-sensing front ends, BLE connectivity, and wireless charging in wrist-worn form factors subject to IP-rated enclosure constraints. Our FAE team assists with power budget analysis support parts, RF matching networks, and supply planning for high-volume wearable launches.
- GNSS/LTE antennas, low-power LDOs, and 0201/0402 passives in stock
- 24-hour RFQ with BOM matching for IoT and wearable product lines
- Ultra-low-power component selection support from Restar engineers
- Global shipping for rapid prototype and mass-production fulfillment

Key Challenges
Extreme Power Budget Constraints
Coin-cell and thin-film battery devices require sub-μA sleep currents across every component in the power tree.
Antenna Performance in Compact Enclosures
Metal watch cases and plastic tracker housings detune antennas, requiring careful matching network and radiator selection.
Multi-Radio Coexistence
Trackers combining GNSS, cellular, and BLE must manage RF isolation and shared antenna architectures on minimal PCB area.
Application Scenarios
Asset & Logistics Tracking
Fleet trackers, cold-chain monitors, and shipping container tags report location and sensor data over LTE-M, NB-IoT, or LoRaWAN networks. Restar supplies GNSS antennas, cellular module passives, and nano-power LDOs for tracker PCBA.
- GNSS patch and FPC antennas
- LTE-M/NB-IoT module companion parts
- Nano-quiescent LDO and load switches
Health & Fitness Wearables
Smartwatches, fitness bands, and medical wearables acquire PPG, ECG, and motion data through bio-sensing front ends with BLE cloud sync. We provide optical sensor support, precision passives, and compact charging ICs.
- PPG/ECG analog front-end support
- BLE SoC companion passives
- Compact wireless charging receiver ICs
LPWAN Sensor End Nodes
Smart agriculture, utility metering, and building sensors transmit data over LoRa, Sigfox, or Wi-SUN with multi-year battery life targets. Restar delivers Sub-GHz antennas, energy harvesting support, and long-life tantalum/MLCC alternatives.
- Sub-GHz PCB and wire antennas
- Energy harvesting PMIC support
- Wide-temperature MLCC and resistors
