SF32LB58-DevKit-LCD¶

Overview¶

The SF32LB58-DevKit-LCD is a flagship development board built around the SF32LB58-MOD module family. It is intended for products that use DSI, DPI/RGB, or QSPI displays and need a practical bring-up platform for high-resolution UI, audio, storage, USB, and peripheral integration.

The board brings together the SF32LB58x module, multiple display connectors, analog microphone input, stereo speaker output, MicroSD, dual USB Type-C ports, large-core and low-power-core expansion headers, and accessory interfaces such as CAN and SDIO Wi-Fi expansion.

This makes it a strong fit for high-end wearable HMIs, rich dashboards, connected control panels, and other products that need to validate display, storage, audio, and external-peripheral behavior before committing to a custom flagship board.

Board and Module Version Notes¶

Confirm the exact module and board silkscreen revision before choosing a firmware target, storage assumption, or debug wiring plan.

Board Highlights¶

• SF32LB58-MOD-N16R32N1 or SF32LB58-MOD-A128R32N1 module, depending on board version
• Standard SF32LB586VDD36 platform with dual 16MB HPI-PSRAM and 1MB in-package QSPI-NOR
• Additional 16MB QSPI-NOR or 128MB QSPI-NAND, depending on module variant
• 48MHz main crystal and 32.768kHz RTC crystal
• IPEX antenna connector and module RF matching network
• MIPI DSI / RGB888 display support through dedicated FPC connectors
• Dual QSPI / DSPI / SPI display paths exposed through 40-pin headers
• I2C touch-panel support
• On-board analog microphone input and stereo Class-D audio output
• Two USB Type-C ports: one for USB-to-UART download/debug, one for USB2.0 HS
• MicroSD card slot over SDIO
• Large-core and low-power-core GPIO expansion through two 40-pin headers
• CAN and SDIO Wi-Fi expansion capability

When to Use This Board¶

Choose SF32LB58-DevKit-LCD when the project needs a realistic high-end display and peripheral validation platform rather than a minimal breakout board.

• Bring up MIPI DSI, RGB888, or QSPI display panels
• Validate touch, audio, storage, and USB together
• Test high-resolution UI behavior on the SF32LB58x platform
• Evaluate CAN or SDIO Wi-Fi expansion
• Compare NOR and NAND-backed module configurations
• Validate firmware on a flagship-class board before custom PCB work

Hardware Configuration¶

Getting Started¶

Required Hardware¶

• SF32LB58-DevKit-LCD board
• LCD module using MIPI DSI, RGB888, or QSPI, as appropriate
• USB 2.0 data cable, Type-A to Type-C or equivalent
• Host computer running Windows, Linux, or macOS

Optional Hardware¶

• Two speakers
• TF / MicroSD card
• J-Link or compatible SWD debugger
• CAN transceiver board
• SDIO Wi-Fi module

Basic Setup¶

1. Connect the target display panel to the correct LCD connector.
2. Connect the USB-to-UART Type-C port to the host computer.
3. Open SiFli's download tool and select the correct COM port.
4. Install or remove the Mode jumper depending on whether you want download mode or normal run mode.
5. Power the board and download or run the target firmware.
6. After display bring-up, validate touch, audio, storage, and any expansion peripherals required by the product.

Use a real data-capable USB cable. Some Type-C cables provide power only and will not expose the UART or USB data path.

Power¶

SF32LB58-DevKit-LCD is powered from USB Type-C.

• Both on-board USB Type-C connectors can supply power to the board
• For firmware download and UART logging, use the USB-to-UART Type-C port
• Plan the USB2.0 HS Type-C port separately when validating native USB functions

Download and Debug¶

The primary firmware download and serial-log interface is the USB-to-UART Type-C port.

• Download mode: install the Mode jumper, then power or reset the board
• Software debug/log mode: remove the Mode jumper, then power or reset the board

The board also supports J-Link / SWD debug.

Key Module and Expansion Signals¶

The board exposes both module-level signals and two 40-pin expansion headers. Use the module datasheet and schematic package for the exhaustive pin map; the summary below covers the most design-relevant groups.

Display Interfaces¶

The board supports three main display paths:

• MIPI DSI through a 30-pin, 0.5mm-pitch FPC connector
• RGB888 through a 40-pin, 0.5mm-pitch FPC connector compatible with a common 正点原子-style pin order
• QSPI / DSPI / SPI through the two 40-pin expansion headers

Supported display guidance from the SiFli source includes:

• MIPI DSI panels up to 2-lane transfer and up to 1280 × 800 resolution
• RGB888 panels up to 1280 × 800 resolution
• QSPI panels up to 512 × 512 resolution

Audio¶

The board supports:

• One on-board microphone input path
• Two audio ADC input paths, with one multiplexed against the on-board microphone path
• Two speaker outputs
• One PDM signal path that is multiplexed with RGB signals and therefore unavailable while the RGB display path is active

CAN and SDIO Wi-Fi Expansion¶

The underlying SF32LB58 module includes a CAN controller, and the board exposes the interface for use with an external transceiver.

The board also supports SDIO Wi-Fi expansion through the header interface.
