7. serve good engineering practice standards 6 1 CE ETSI EU The UDB Mini Development Board and all original parts of the Embedded RFID Starter Kit comply with applicable EN ISO standards Nonetheless the person handling the module s has to make sure that all requirements are met during customized use and especially by the final product It is his obligation to declare product conformity We recommend to assign this task to a qualified third party test lab specialized on EMC measurements 6 2 FCC USA The UDB Mini Development Board and all original parts of the Embedded RFID Starter Kit comply with Part 15 of the FCC Rules The person handling the module s has to make sure that all requirements are met during customized use To fulfill all FCC requirements the person handling the module s must test the final product to comply with FCC regulations regarding intentional and unintentional radiators before declaring FCC compliance of his own product 6 3 IC Canada Certification requirements for Industry Canada IC are similar to those of the FCC Limits of ICES 003 for radiated emissions are similar to the formats specified in FCC Part 15 and CISPR 22 Industry Canada accepts FCC test reports or CISPR 22 test reports for compliance with ICES 003 The integrator is responsible for its product to comply with all relevant IC rules Technical Documentation metraTec UDB Mini Page 9 of 11 7 Version History Version Chan
8. shake Flow control The UART commands used to control the modules are described in different metraTec protocol guides depending on the module used Technical Documentation metraTec UDB Mini Page 7 of 11 5 Digital Inputs Outputs GPIOs The modules typically have eight freely configurable input output pins which can be set and read via the respective module To use these GPIOs just connect your signals to the corresponding vias X3 All signals are 5 V DC signals A ATTENTION Please make sure that you only connect 5 V level devices to the GPIOs or use the right level shifter if connecting other devices Some devices use 12 V or even 24V DC inputs outputs If you connect these without proper protection this will most likely destroy the module currently plugged in Pin Pin Function X3 1 GND X3 2 Input Output O X3 3 Input Output 1 X3 4 Input Output 2 X3 5 Input Output 3 X3 6 Input Output 4 X3 7 Input Output 5 X3 8 Input Output 6 X9 Input Output 7 Tab 2 Overview of digital input output pins Technical Documentation metraTec UDB Mini Page 8 of 11 6 Certification The UDB Mini is an evaluation board intended for use for ENGINEERING DEVELOPMENT DEMONSTRATION OR EVALUATION PURPOSES ONLY and is not considered by metraTec to be a finished end product fit for general consumer use Persons handling the product s must have electronics training and ob
