Key features
- MPU-6050 sensor (
U1) in a 24-pin QFN package. - Board outline 25.44 × 22.86 mm, with 1.59 mm nominal PCB thickness in the KiCad file.
- Two parallel four-pin I²C connectors,
J2andJ3. - Eight-pin, 2.54 mm header
J1exposing I²C,AD0/SD0,CLKIN,INT, andFSYNC. - Onboard 4.7 kΩ pull-ups from SDA and SCL to
+3.3V.
Pin configuration
J2 and J3 have the same connections. They are two access points to one I²C bus, not separate channels.
The eight-pin header
J1 adds the sensor control signals. Numbers are PCB pad numbers; use the board’s pin-1 mark for physical orientation.
Solder jumpers and I²C address
All three solder-jumper footprints are marked open in the KiCad design. Confirm their actual state on the assembled board.The MPU-6050 product specification defines 7-bit I²C address
0x68 when AD0 is low and 0x69 when AD0 is high. With JP2 open, this board design shows no populated pull-up or pull-down on AD0/SD0, so it does not establish a reliable default address. Set or verify the AD0 connection first, then scan the I²C bus. FSYNC and CLKIN are also exposed when their jumpers are open; drive or configure them according to the sensor datasheet and application.Connect to a Glyph board
- Power both boards off. Connect GS007
GND,+3.3V,SDA, andSCLto the corresponding 3.3 V I²C pins on the Glyph board, using eitherJ2,J3, orJ1. - Inspect
JP2and establish a definedAD0/SD0level before expecting reliable address detection. - Power the boards and run the I²C scanner to find the address actually selected by the assembled board.
- Configure the sensor’s measurement range, filtering, sample rate, and calibration in the host application.
JP2 open, or a tested calibration. For connector orientation and component placement, use the GS007 schematic and PCB layout.
