From 8f9661e8e4d78eb3c8b53958de18917f780ab6d7 Mon Sep 17 00:00:00 2001 From: Tang ZZ Date: Wed, 9 Sep 2026 19:46:56 +0800 Subject: [PATCH] docs(penta-sata-hat): document onboard 2-pin 5V fan header spec Add specification for the 2-pin fan header on the Penta SATA HAT base board (JST GH 1.25mm, fixed 5V, non-PWM), located next to the 12V DC power jack. Source: confirmed customer question (2026-09-09 support thread) where docs lacked this connector spec; Radxa Team forum staff posts confirm JST GH 1.25mm 2-pin / 5V fan header. zh+en synced. --- docs/accessories/storage/penta-sata-hat/README.md | 15 +++++++++++++++ .../accessories/storage/penta-sata-hat/README.md | 15 +++++++++++++++ 2 files changed, 30 insertions(+) diff --git a/docs/accessories/storage/penta-sata-hat/README.md b/docs/accessories/storage/penta-sata-hat/README.md index ec82a6c77..6b3d9ca9c 100644 --- a/docs/accessories/storage/penta-sata-hat/README.md +++ b/docs/accessories/storage/penta-sata-hat/README.md @@ -122,10 +122,25 @@ Penta SATA HAT 系列通常由以下部分组成： | 9 | GND | 10 | NC | **技术规格：** + - **连接器类型：** 2x5 针座子 - **针距 (Pitch)：** 2.0mm - **兼容连接器：** 标准 2.0mm 间距 2x5 针排针 (2x5 pin header, 2.0mm pitch) +## 板载风扇接口 + +Penta SATA HAT 底板在 12V DC 电源座旁提供了一个 2-pin 风扇接口（位于板底），规格如下： + +- **连接器类型：** JST GH 1.25mm 2-pin 公座 +- **针距 (Pitch)：** 1.25mm +- **兼容连接器：** JST GH 1.25mm 2-pin 母座（线对板连接器） +- **输出电压：** 固定 5V（5V + GND），请使用 5V 风扇，上电前注意极性 +- **控制方式：** 非 PWM，上电即常转；如需 PWM 调速，请使用可选的 [Penta SATA HAT TOP 板](./sata-hat-top-board.md)（通过 2x5 座子上的 PWM 信号控制） + +:::caution +请不要强行插入 2.0mm 间距（如 JST PH）的插头，1.25mm 与 2.0mm 不兼容。 +::: + ## 用户指南 diff --git a/i18n/en/docusaurus-plugin-content-docs/current/accessories/storage/penta-sata-hat/README.md b/i18n/en/docusaurus-plugin-content-docs/current/accessories/storage/penta-sata-hat/README.md index 8a1430b9a..965d0e9b3 100644 --- a/i18n/en/docusaurus-plugin-content-docs/current/accessories/storage/penta-sata-hat/README.md +++ b/i18n/en/docusaurus-plugin-content-docs/current/accessories/storage/penta-sata-hat/README.md @@ -122,10 +122,25 @@ If you run into installation or boot problems, identify which combination you ar | 9 | GND | 10 | NC | **Technical Specifications:** + - **Connector Type:** 2x5 pin header - **Pitch:** 2.0mm - **Compatible Connectors:** Standard 2.0mm pitch 2x5 pin header (2x5 pin header, 2.0mm pitch) +## Onboard Fan Header + +The Penta SATA HAT base board provides a 2-pin fan header right next to the 12V DC power jack (on the underside of the board).
