MPU-6500 from TDK InvenSense, in a QFN-24-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	NC	unconnected	No Connect. Do not connect.
2	NC	unconnected	No Connect. Do not connect.
3	NC	unconnected	No Connect. Do not connect.
4	NC	unconnected	No Connect. Do not connect.
5	NC	unconnected	No Connect. Do not connect.
6	NC	unconnected	No Connect. Do not connect.
7	AUX_CL	output	Auxiliary I2C master serial clock, for connecting an external sensor (e.g. magnetometer). Push-pull output driven by the on-chip I2C master.
8	VDDIO	power_in	Digital I/O supply voltage. Independent from VDD; sets the logic levels of the primary and auxiliary serial interfaces. Bypass to GND with a 10 nF capacitor.
9	AD0/SDO	bidirectional	In I2C mode: slave-address LSB (AD0) - selects 7-bit slave address 0x68 or 0x69. In SPI mode: SPI serial data output (SDO / MISO).
10	REGOUT	passive	Regulator filter capacitor connection. Attach a 0.1 uF X7R ceramic capacitor to GND. Do not drive externally.
11	FSYNC	input	Frame synchronization digital input. Connect to GND if unused; otherwise drive with a logic-level frame-sync pulse referenced to VDDIO.
12	INT	output	Interrupt digital output (programmable as totem-pole push-pull or open-drain, active-high or active-low). Signals data-ready, motion, FIFO overflow and other events; should be routed to a host GPIO capable of waking the AP.
13	VDD	power_in	Main power supply voltage (1.71 V to 3.45 V) for the analog core, gyro and accelerometer. Bypass to GND with a 0.1 uF X7R ceramic capacitor.
14	NC	unconnected	No Connect. Do not connect.
15	NC	unconnected	No Connect. Do not connect.
16	NC	unconnected	No Connect. Do not connect.
17	NC	unconnected	No Connect. Do not connect.
18	GND	power_in	Power supply ground. Common return for VDD and VDDIO; also serves as the device thermal/mechanical reference.
19	RESV	unconnected	Reserved. Do not connect.
20	RESV	passive	Reserved. Connect to GND.
21	AUX_DA	bidirectional	Auxiliary I2C master serial data, for connecting an external sensor (e.g. magnetometer). Open-drain; requires an external pull-up to VDDIO.
22	nCS	input	SPI chip-select (active low, SPI mode only). Also used at power-up as the interface-mode select: tie high through a pull-up for I2C operation, drive low for SPI transactions.
23	SCL/SCLK	input	I2C serial clock (SCL) or SPI serial clock (SCLK). Muxed function selected by the interface mode chosen at power-up.
24	SDA/SDI	bidirectional	I2C serial data (SDA, open-drain bidirectional) or SPI serial data input (SDI / MOSI). Muxed function selected by the interface mode chosen at power-up.
