# glove ## Description Glove interface board using Seeed Studio XIAO ESP32S3. Manufacturing path updated for partial assembly: preserve existing glove interface circuitry (FSR inputs on J3-J7, I2C on J8, SPI on J9, pull resistors R1-R7, decoupling C1) and source U1 separately because JLCPCB stock for MPN 113991114 is unavailable. Assemble all other parts normally, leave U1 for customer-supplied/manual installation, and do not substitute U1 unless a verified XIAO-format pin-compatible replacement is explicitly approved. ## Project Details - **Owner:** opengraph-beomsoo - **Created:** 3/26/2026 - **Last Updated:** 3/29/2026 - **Visibility:** Public - **Allow Substitutes:** No - U1 requires verified XIAO-format pin compatibility - **System Architecture:** flowchart TD subgraph MCU_Block [MCU] MCU_XIAO["Seeed XIAO ESP32-S3"] end subgraph FSR_Block [FSR Inputs] FSR1["FSR1 Connector J3"] FSR2["FSR2 Connector J4"] FSR3["FSR3 Connector J5"] FSR4["FSR4 Connector J6"] FSR5["FSR5 Connector J7"] PD1["Pulldown R1 10k"] PD2["Pulldown R2 10k"] PD3["Pulldown R3 10k"] PD4["Pulldown R4 10k"] PD5["Pulldown R5 10k"] end subgraph I2C_Block [I2C Breakout] I2C_J8["I2C Connector J8"] PU_SDA["Pullup R6 4.7k"] PU_SCL["Pullup R7 4.7k"] end subgraph SPI_Block [SPI Breakout] SPI_J9["SPI Connector J9"] end subgraph Power_Block [Power] V33["3.3V Rail"] GND["GND"] DEC["Decoupling C1 100nF"] end MCU_XIAO -->|"D0-D4"| FSR1 MCU_XIAO -->|"D0-D4"| FSR2 MCU_XIAO -->|"D0-D4"| FSR3 MCU_XIAO -->|"D0-D4"| FSR4 MCU_XIAO -->|"D0-D4"| FSR5 MCU_XIAO -->|"D6 SDA"| I2C_J8 MCU_XIAO -->|"D7 SCL"| I2C_J8 MCU_XIAO -->|"D5 CS"| SPI_J9 MCU_XIAO -->|"D8 SCK"| SPI_J9 MCU_XIAO -->|"D9 MISO"| SPI_J9 MCU_XIAO -->|"D10 MOSI"| SPI_J9 V33 --> FSR1 V33 --> FSR2 V33 --> FSR3 V33 --> FSR4 V33 --> FSR5 V33 --> I2C_J8 V33 --> SPI_J9 V33 --> DEC GND --> PD1 GND --> PD2 GND --> PD3 GND --> PD4 GND --> PD5 GND --> I2C_J8 GND --> SPI_J9 GND --> DEC - **Implementation Details:** Partial assembly approved for U1 only. Populate all components except U1. Source Seeed Studio XIAO ESP32S3 (MPN 113991114) separately from Digi-Key or Mouser and install manually after assembly. Preserve existing glove interface circuitry without netlist changes. - **Copies:** 1 ## Key Components ### J3 — [S2B-PH-K-S(LF)(SN)](https://www.flux.ai/adrian95/s2b-ph-k-slfsn~brb.md) - Role: Connector - Package: THT - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Connector - Manufacturer Name: JST Sales America Inc. - Datasheet URL: https://www.jst-mfg.com/product/pdf/eng/ePH.pdf - Manufacturer Part Number: S2B-PH-K-S(LF)(SN) - Role Details: JST PH 2-pin for FSR1 **Pins:** - P1 [pin 1] - P2 [pin 2] ### J4 — [S2B-PH-K-S(LF)(SN)](https://www.flux.ai/adrian95/s2b-ph-k-slfsn~brb.md) - Manufacturer Part Number: S2B-PH-K-S(LF)(SN) - License: https://creativecommons.org/licenses/by/4.0/ - Package: THT - Part Type: Connector - Manufacturer Name: JST Sales America Inc. - Datasheet URL: https://www.jst-mfg.com/product/pdf/eng/ePH.pdf - Role Details: JST PH 2-pin for FSR2 - Role: Connector **Pins:** - P1 [pin 1] - P2 [pin 2] ### J5 — [S2B-PH-K-S(LF)(SN)](https://www.flux.ai/adrian95/s2b-ph-k-slfsn~brb.md) - Manufacturer Part Number: S2B-PH-K-S(LF)(SN) - Datasheet URL: https://www.jst-mfg.com/product/pdf/eng/ePH.pdf - Role Details: JST PH 2-pin for FSR3 - Manufacturer Name: JST Sales America Inc. - Part Type: Connector - License: https://creativecommons.org/licenses/by/4.0/ - Package: THT - Role: Connector **Pins:** - P1 [pin 1] - P2 [pin 2] ### J6 — [S2B-PH-K-S(LF)(SN)](https://www.flux.ai/adrian95/s2b-ph-k-slfsn~brb.md) - Datasheet URL: https://www.jst-mfg.com/product/pdf/eng/ePH.pdf - Manufacturer Name: JST Sales America Inc. - Part Type: Connector - License: https://creativecommons.org/licenses/by/4.0/ - Role Details: JST PH 2-pin for FSR4 - Manufacturer Part Number: S2B-PH-K-S(LF)(SN) - Package: THT - Role: Connector **Pins:** - P1 [pin 1] - P2 [pin 2] ### J7 — [S2B-PH-K-S(LF)(SN)](https://www.flux.ai/adrian95/s2b-ph-k-slfsn~brb.md) - Package: THT - Manufacturer Part Number: S2B-PH-K-S(LF)(SN) - Role Details: JST PH 2-pin for FSR5 - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Connector - Role: Connector - Manufacturer Name: JST Sales America Inc. - Datasheet URL: https://www.jst-mfg.com/product/pdf/eng/ePH.pdf **Pins:** - P1 [pin 1] - P2 [pin 2] ### J8 — [61300411121](https://www.flux.ai/adrian95/61300411121~pw9.md) - Manufacturer Part Number: 61300411121 - Role: Connector - Package or Case Code: HDRV4W95P0X254_1X4_1016X254X854P - Datasheet URL: https://www.we-online.com/components/products/datasheet/61300411121.pdf - Manufacturer Name: Wurth Elektronik - Part Type: Connector - Package: THT - Role Details: I2C header: VCC,GND,SDA,SCL - License: https://creativecommons.org/licenses/by/4.0/ **Pins:** - 1 [pin 1] - 2 [pin 2] - 3 [pin 3] - 4 [pin 4] ### J9 — [Pin Header 01x06 2.54mm Vertical](https://www.flux.ai/adrian95/pin-header-01x06-2p54mm-vertical~lzd.md) - Role Details: SPI header: VCC,GND,SCLK,MOSI,MISO,CS - Role: Connector - Part Type: Connector - Package: THT - License: https://creativecommons.org/licenses/by/4.0/ **Pins:** - Pin_1 [pin 1] - Pin_2 [pin 2] - Pin_3 [pin 3] - Pin_4 [pin 4] - Pin_5 [pin 5] - Pin_6 [pin 6] ### U1 — [Seeed Studio XIAO ESP32S3](https://www.flux.ai/seeedstudio/seeed-studio-xiao-esp32s3~jt.md) - Package: Module - Digi-Key Part Number: 1597-113991114-ND - Allow Substitutes: No - Part Type: Microcontroller - Role Details: Seeed XIAO ESP32-S3 module; all D0-D10 used - Manufacturer Name: Seeed Studio - Purchase Url: https://www.seeedstudio.com/XIAO-ESP32S3-p-5627.html - Product Info Url: https://wiki.seeedstudio.com/xiao_esp32s3_getting_started/ - Mouser Part Number: 713-113991114 - Implementation Details: Do not place through JLCPCB SMT inventory if unavailable.
