SF32LB52-LCHSPI-ULP

Board sf32lb52-lchspi-ulp is based on the 立创·黄山派 development board (SF32LB52-黄山派), which is designed as a smart watch / smart band reference design, and has module SF32LB52X-MOD-1-N16R8 on the board. The module integrates SoC SF32LB525UC6 with 16MB QSPI-NOR Flash and 8MB OPI-PSRAM.

Main on-board resources:

• 1.85-inch 390x450 QSPI AMOLED display (driver IC CO5300) with capacitive touch panel

• Audio: on-board MEMS microphone and Class-D audio power amplifier, with a GH-1.25mm connector for an external speaker (up to 3W/4Ω or 2W/8Ω)

• Keys: KEY1 power key (PA34, long-press to reset) and KEY2 function key (PA43)

• USB Type-C to UART for program download and debug; SPI interface TF card slot

• RGB LED, motor driver, 6-axis IMU (LSM6DS3TR-C), 3-axis magnetometer (MMC5603NJ) and ambient light sensor (LTR-303ALS-01)

• 30-pin 1.27mm expansion header exposing GPIOs, power rails and debug UART
