Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | GND | power_in | Ground reference. |+| 2 | SCS | input | SPI chip select input (SSEL), active low. Asserted by the SPI master to select the WK2124. |+| 3 | SCLK | input | SPI clock input from the master. WK2124 operates in SPI slave mode, SPI mode 0, up to 10 Mbit/s. |+| 4 | SDIN | input | SPI serial data input (MOSI) from the master. |+| 5 | SDOUT | output | SPI serial data output (MISO) to the master. |+| 6 | RX4 | input | UART sub-channel 4 serial data input. |+| 7 | TX4 | output | UART sub-channel 4 serial data output. |+| 8 | /RST | input | Hardware reset input, active low. |+| 9 | VCC | power_in | Positive supply, 2.5 V to 5.0 V. |+| 10 | /IRQ | output | Interrupt request output, active low. Open-drain style; datasheet recommends an external pull-up (~5.1 kΩ typical). |+| 11 | TX2 | output | UART sub-channel 2 serial data output. |+| 12 | RX2 | input | UART sub-channel 2 serial data input. |+| 13 | GND | power_in | Ground reference. |+| 14 | TX1 | output | UART sub-channel 1 serial data output. |+| 15 | RX1 | input | UART sub-channel 1 serial data input. |+| 16 | TX3 | output | UART sub-channel 3 serial data output. |+| 17 | RX3 | input | UART sub-channel 3 serial data input. |+| 18 | VCC | power_in | Positive supply, 2.5 V to 5.0 V. |+| 19 | OSCI | input | Crystal oscillator input. A 1 MΩ resistor should be placed in parallel with the crystal. |+| 20 | OSCO | output | Crystal oscillator output. Connects to the opposite terminal of the crystal from OSCI. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | WEIKAI |+| Package | SSOP-20-208mil |+| Category | Interface |+| Pins | 20 |++## Ordering variants++Same part, different packaging or reel option.++- `WK2124-ISSG`++## CAD (KiCad official)++- Symbol: `WK2124-ISSG`+- Footprint: `Package_SO:SSOP-20_5.3x7.2mm_P0.65mm`+- 3D model: SSOP-20-208mil (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [WEIKAI datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8586180009564786688) (21 pp, sha256 `61ccd637c44923b3`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
