Important

  1. SF32LB52-DevKit-ULP is compatible with SF32LB-MOD-1 module。

  2. The VDD33_VOUT pin 17 of the module is a 3.3V power output, no output by default, internal LDO enable needs to be turned on by software。

  3. The VBAT pin 27 of the module is the power input pin, which can be directly connected to a lithium battery. When not using battery power supply but using constant voltage power supply, the input range is 3.7V~4.7V, it is recommended to connect to 3.8V。

  4. The startup threshold of the VBAT power supply of the SF32LB-MOD-1-N16R8 module is set to 3.58V by software, and the shutdown threshold is set to 3.48V by software。

  5. Pins 62~68 of the SF32LB-MOD-1-N16R8 module are by default internally connected to Nor Flash in the module, the development board cannot use them if you want to use the SDIO interface, please choose a flash-free version of the module。

Important

  1. Pins 1 and 2 of the 30p are connected to the USB-TypeC V。

  2. 30p的5脚是连接在开发板的Battery座上，未和下游连接，工作时需要用跳线帽把VBAT_S和VBAT短接。

  3. 30p的6脚是连接在开发板的充电IC的VBAT引脚和模组的VBATS引脚上，这里把VBAT_S和VBAT断开是为了方便串电流表测试功耗。

  4. 30p的7脚是连接在开发板的充电IC的VSYS引脚上，未和下游连接，工作时需要用跳线帽把VSYS_S和VSYS短接。

  5. 30p的8脚是连接在模组的VSYS引脚和其他VSYS输入引脚上，这里把VSYS_S和VSYS断开是为了方便串电流表测试功耗。

  6. 30p的11脚是连接在开发板的VSYS_1转VCC_3V3的LDO输出引脚上，未和下游连接，工作时需要用跳线帽把VCC_3V3_S和VCC_3V3短接。

  7. 30p的12脚是连接在开发板的的VCC_3V3主电上，这里把VSYS_S和VSYS断开是为了方便串电流表测试功耗。

Power supply instructions

The SF32LB52 Huangshan Development Board has two power supply methods: USB Type-C and battery power supply.

  1. The USB Type-C interface on the board can power the board.

  2. The battery can be powered independently, which is convenient for running independently without a computer.

Hardware setting options

Connect the USB cable through the USB-to-UART port, open the program download tool from Sifli Technology, and select the corresponding COM port and program.

  1. Download mode

  • Check the BOOT option, power on, enter the download mode after booting, and the program download can be completed.

  1. Software development mode

  • Uncheck the BOOT option, power on, enter the serial port log printing mode after booting, and then enter the software debugging mode.

  1. Reset

  • Reset the module by pulling down and then up the RTS# pin of CH340N.

Charging and battery selection

The SF32LB52-Huangshan Development Board integrates the SY6103 linear charging chip, which supports a maximum charging current of 500mA and is set to 450mA constant current by default.

It is recommended to choose a single-cell polymer lithium battery with a capacity of 450mAh~500mAh. The battery interface is a GH-1.25mm female socket with forward wiring sequence. Please refer to the battery seat silkscreen on the development board for polarity.

LCD display interface

The SF32LB52-Huangshan core board supports QSPI interface LCD screens, with a connector of 22p-0.5pitch FPC, and dual contact points at the top and bottom. Please refer to the above definition for signal line sequence. If the line sequence is different, an adapter board test is required. Please refer to the “SF32LB52-DevKit-LCD Adapter Board Production Guide”.

Audio interface

The SF32LB52-Huangshan core board integrates MEMS MIC and audio amplifier chips.

  • Supports audio signal input from the onboard mic.

  • Supports external speakers (up to 3W/4 ohms), speaker connector specifications (GH-1.25mm female socket).

Sample acquisition

Contact the FAE of Sifli Technology to obtain the development board.
