www.nicerf.cn STP201 NiceRF Wireless Technology Co., Ltd. Rev 2.0 sales@nicerf.com -3- 1. Description: STP201 isa 3D pedometermodulewith functional IC chipsetwhich includeaG-sensor andMCU. It has adopted the standard IIC interface, with the 3D MEMS sensor (G sensor) and high precision of 3D pedometer algorithm, it can give a precisely pedometer in any direction. This chipset has the characteristicsofsmallsize,lowpowerconsumptionandetc.ThestandardI2C digitalinterfaceensuresit canbeeasilyembeddedinvariouskindsofpedometerfunctionalsystem. ★Note: The algorithm of our pedometer is adjustable according to customer’s requirement. We can provide the pedometer for shoes, table class pedometer and bracelet pedometer wearing on wrist, pedometer wearing on waist and pedometer putting inside the pocket. Pls indicate clearly when purchasing. 2. Features: IICinterface Highprecision3Dpedometeralgorithm Wristapplication Ultra-lowpower/Ultra-smallsize 3.

There are some limitations when the module is wakeupbyI2Cinterface.Forthefirst“start”commandoftheI2Cprotocol,theSCLwillhavetohold atleast500ustowakeupMCU.ThemaximumI2Cclockis100KHz. Also: STEP_OUT: The chipset can output the pulse for each step action, the high level of the pulse signalisaround50ms.
