StarFlash Module

Ebyte StarFlash (SparkLink) Module Selection Guide

StarFlash (SparkLink) is a new-generation short-range wireless technology that combines the advantages of Bluetooth and Wi-Fi, featuring ultra-high speed, ultra-low latency and superior reliability with lower power consumption than Bluetooth. It supports both SLE (SparkLink Low Energy) and SLB (SparkLink High Speed) modes.

Ebyte StarFlash product portfolio includes single-mode SLE modules and Wi-Fi/BLE/SLE tri-mode combo modules, widely applied in smart automotive, consumer electronics and intelligent manufacturing scenarios to deliver efficient and stable wireless connectivity for IoT and smart connected environments.

How to Select StarFlash Module?

4-Point Quick Selection Guide

Select by protocol combination first. Choose the E105-BS21 single-mode series if you only need StarFlash SLE connectivity; choose the E105-WBS36 tri-mode series for projects requiring Wi-Fi 6, Bluetooth LE and StarFlash in one module.
Match transmit power and range to deployment scale. For short-range wearable and consumer devices, select the 6dBm / 270m BS21 series; for industrial and long-range IoT scenarios, select the 20dBm / 1000m WBS36 series.
Choose antenna type based on integration design. Select on-board PCB antenna models for simplified layout and reduced BOM cost; select IPEX or SMD PIN models for flexible external antenna placement and optimized RF performance.
Align package size with board space. The ultra-compact 10×10mm E105-WBS36S is ideal for space-constrained devices; standard SMD/stamp hole packages fit most conventional embedded designs.
