What is dBM?

From Spec sheet, we can find the output power always stated as dBM.

For example:

Nordic nRF52832

Transmitting power (+4dBM~-20dBM) / Receiving Sensitivity (-96dBM)

dBm is the unit for radiowave, it is a way to express the comparison between the reference signal value

The reference value is 0dBM at 1mW, the unit represented as shown below

1/10000 times = -40 dBm

1/1000 times = -30 dBm

1/100 times = -20 dBm

1/10 times = -10 dBm

1mW =     0 dbm ← Reference Signal Value

10 times  =  10 dBm

100 times  =  20 dBm

1000 times  =  30 dBm

MDBT42 Module (Nordic nRF52832 Solution) Now Launched

MDBT42, based on Nordic nRF52832 WL-CSP solution, is about to be armed and targeting for IoT industry.

Raytac’s module line in 2016 now has become ready and all well loaded.

Targeting next-generation wearables and space-constrained IoT applications, the nRF52832 Wafer Level Chip Scale Package (WL-CSP) has a super-compact 3.0 by 3.2mm footprint that occupies one quarter of the footprint area of Nordic’s standard 6.0 by 6.0mm QFN48-packaged nRF52832, yet offers the same full feature set

Oslo, Norway 2016/07/05

Nordic Semiconductor today announces the availability of a Wafer Level Chip Scale Package (WL-CSP) variant of its nRF52832 Bluetooth® low energy (formerly known as Bluetooth Smart) System-on-Chip (SoC) that occupies a quarter of the footprint area of the standard-packaged Nordic nRF52832 and targets next-generation, high-performance wearables and space-constrained IoT applications.

The nRF52832 WL-CSP has a super-compact 3.0 by 3.2mm footprint compared to the standard 6.0 by 6.0mm footprint of its larger but conventionally-packaged nRF52832 QFN48 cousin, yet offers the same full single-chip feature set and best-in-class, ultra-low-power application operation. This includes a powerful on-board 64MHz ARM® Cortex®-M4F processor that enables protocol and application task processing to be completed in unprecedentedly short time-frames, thus allowing power-saving sleep modes to be entered much quickly compared to competing devices.

Like the nRF52832, the nRF52832 WL-CSP features: 512kB Flash and 64kB RAM; on-chip NFC™ tag for consumer-friendly Touch-to-Pair; best-in-class ultra-high performance, ultra-low-power multi-protocol Bluetooth low energy, ANT™, and proprietary 2.4GHz radio; 5.5mA peak RX/TX currents; an on-chip RF Balun; plus a unique fully-automatic power management system that makes achieving optimal power consumption easy for designers.

The nRF52832 WL-CSP is compatible with Nordic’s Bluetooth 4.2 stacks and supporting SDKs including the latest S132 multi-role concurrent software stack, nRF5 SDK, nRF5 SDK for HomeKit, and nRF5 SDK for AirFuel (resonant wireless charging).

“The availability of a super-compact footprint nRF52832 brings new design opportunities to wearables and other space-constrained IoT applications,” comments Kjetil Holstad, Product Manager Ultra Low-Power Wireless at Nordic Semiconductor. “And this SoC is available now in high production volumes for immediate inclusion in upcoming product development.”

Holstad adds: “The evolution of wearables to date has only ever gone one way: ever increasing performance and functionality in ever-slimmer, lighter, form factors. The nRF52832 WL-CSP is by a clear margin, the smallest and most advanced Bluetooth low energy SoC available on the market today.”

有關 FuTKEE 與 RED

近來, 很多使用勁達國際電子藍牙模組的客戶提到 FuTKEE 與RED
 基本上, FuTKEE指的就是新的CE無線指令RED,但目前都還是Draft都還在修正,目前還無法執行
 預計2016年底或2017年初,才會有比較明確的消息,針對所有的無線產品都會有改動
 
最新歐洲無線設備指令2014/53/EU
在新無線設備指令(RED)中和舊RTTE指令的重大區別有:
  • RED產品范圍僅包括無線通讯和無線識别設備(如RFID,雷達,移動偵测等)。射频設備不用於通讯或者識别的會在電磁兼容EMC指令和低電壓LVD指令的管控中
  • 有線通訊終端設備(TTE)被移除,因此RED指令僅用於無線產品
  • 無線廣播接收機現已纳入RED指令的範圍(之前涵蓋在電磁兼容EMC指令和低電壓LVD指令中)
  • 指令覆蓋頻率下限已取消(之前RTTE的管控起始頻率是9千赫),而上限依然是3000兆赫
  • 公告機構評估意見現已由型式檢查證書取代
  • 制造商只有在其品質體系經過公告機構评估過後,才能使用附上公告機構號碼的CE標誌(完全品質保証型式高)
  • 二類設備向各國頻譜機構進行通告的要求不再需要
  • 二類設備的標識(驚嘆號)不再需要,不過在某些國家受限使用的警示依然需要出現在產品包装上
  • 不再需要在用户手册中出現CE標誌,不過手册中必须注明射頻使用的頻段及發射功率
  • 個人評估用的套件不再受管控(即不需要進行RED認證)
  • 新指令要求使用統一的充電器
  • 制造商及入口商的地址及聯絡方式必須出現在設備上,而當設備太小時可以出現在用户手册中
現有的這些改動及未来的其他改動将會影響到客戶在今年和未来幾年的產品認証,所以建議從現在就必須開始将新指令考虑到產品的設計和市場销售中
