This is a summary based on public reference documents. For full specifications (timing diagrams, register map, antenna matching guidelines, and erratas), you must refer to the official BK2461 datasheet from Beken Corporation or an authorized distributor. The chip is considered legacy in some markets (replaced by BK2466, BK3632, etc.).
The datasheet highlights a sensitivity of approximately at 250kbps and -82dBm at 2Mbps. While slightly trailing the absolute best-in-class performance of the nRF24L01+ (which can reach -96dBm), the difference is negligible for most consumer applications (wireless mice, keyboards, toys). bk2461 datasheet
Here is an informative review of the BK2461 datasheet and its capabilities. This is a summary based on public reference documents
The chip features hardware CRC (Cyclic Redundancy Check) calculation and acknowledgment handling (Auto-ACK). This is a critical feature defined in the datasheet: it offloads the microcontroller from managing retransmissions. If a packet is not acknowledged, the BK2461 can automatically retry (Auto-Retransmit) based on user-defined register settings, simplifying firmware development significantly. The datasheet highlights a sensitivity of approximately at
This component is commonly found in the inventories of manufacturers like (and generic RF module suppliers). It is widely used in consumer electronics, remote controls, and IoT applications.
For new designs requiring standard 2.4GHz proprietary communication, the BK2461 is a highly recommended, budget-friendly choice. However, engineers should ensure they obtain the specific register map details from the supplier to properly configure the internal crystal oscillator and LNA for optimal performance.
