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 | Vin | power_in | Module power input. Nominal 5.0 VDC (4.75 V min, 5.25 V max) for the CTM1051KT variant. Typical quiescent current 26 mA, max operating current 50 mA. A 10 uF bulk decoupling capacitor to GND is recommended. |+| 2 | GND | power_in | Input-side (controller-side) power ground reference. Common to Vin, TXD and RXD; isolated from CANG on the bus side. |+| 3 | TXD | input | CAN controller transmit data input from the host MCU CAN controller. Logic-level input: VIH >= 2 V, VIL <= 0.8 V (5 V family), drive current 2 mA minimum. Includes a dominant time-out (tto(dom) typ 1 ms) to prevent bus lockup. |+| 4 | RXD | output | CAN controller receive data output to the host MCU CAN controller. Push-pull logic-level output: VOH >= VCC-0.4, VOL <= 0.4 V, output current up to 10 mA. Referenced to input-side GND (pin 2). |+| 6 | CANH | bidirectional | CAN bus high signal line, isolated from the input side by 3500VDC. Dominant level typ 3.5 V, recessive typ 2.5 V. Withstands -58 V to +58 V continuous bus voltage and -150 V to +100 V transients. Complies with ISO/DIS 11898. |+| 7 | CANL | bidirectional | CAN bus low signal line, isolated from the input side by 3500VDC. Dominant level typ 1.5 V, recessive typ 2.5 V. Withstands -58 V to +58 V continuous bus voltage and -150 V to +100 V transients. Complies with ISO/DIS 11898. |+| 8 | CANG | power_out | Isolated bus-side ground reference (isolated power output ground). Reference return for the CANH/CANL bus side; per the typical application (Fig. 1) it is left floating in normal use, and tied to shield/earth only through the recommended surge protection network. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ZLG Zhiyuan Elec |+| Package | DIP-7 |+| Category | IoT/Communication Modules |+| Pins | 7 |++## Ordering variants++Same part, different packaging or reel option.++- `CTM1051KT`+- `CTM1051KAT`++## CAD (KiCad official)++- Symbol: `CTM1051KT`+- Footprint: `Package_DIP:DIP-8-N6_W7.62mm`+- 3D model: DIP-7 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [ZLG Zhiyuan Elec datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588887271306612736) (4 pp, sha256 `51cabad1ee54802d`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
