RTL8762E Evaluation Board User Manual 1. RTL8762E Evaluation Board Introduction 1.1 RTL8762E EVB introduction This document introduces usage of 8762E Bluetooth ® Evaluation Board (EVB) Hardware. 8762E EVB provides hardware environment for customer to develop their own application, which includes: Voltage converter.
2.5V voltage conversion circuit when EVB is powered by Li-ion battery. Mark 9: Power G-sensor and SWD VCC. This jumper must be connected during normal operation. Mark 8: Jumper for RTL8762E overall power consumption test. Remove J23 and cascade with an ammeter when performing overall power consumption test.
RTL8762E Evaluation Board User Manual Mark 4: GND jumper. 1.2.4 IO Port Mark 1: 2 × 15 IO Jumper Mark 19: 2 × 14 IO Jumper 1.2.5 Interface Mark 2: MIC Test Jumper for external MIC Mark 3: UART /LOG Test Jumper.
RTL8762E Evaluation Board User Manual If I2C interface is applied, J18 and J19 should be shorted with jumper. That is to say, connect I2C signal line to M3_2 and M3-3. INT single line can be connected to M2_2 via J20, and can be left not connected if INT function is not configured.
RTL8762E Evaluation Board User Manual Mark 18: RESET key and 5 independent keys, as shown in Figure 1-9. Note: Debouncing capacitors and internal pull-up resistor make up a filter circuit to reduce ripples when buttons are pressed. However, it can also affect the result of keyboard array scan. Capacitors are not mounted on board by default.
VDD_BAT powers VBAT and HVD on EVB. VDD_IO powers VDD_IO on RTL8762E chips (some of packages have no independent VDD_IO Pin) Figure 2-2 Schematic of Power jumpers on EVB J23 shall be disconnected when testing power consumption. Notes: ...
RTL8762E Evaluation Board User Manual When measuring current under the condition of maintaining voltage at 3.0V, external DC power source powers chips instead of onboard power supply. When measuring power consumption, disconnect UART and SWD with debugger to avoid additional impacts from debug device.
