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 | RXD | output | CAN receive data output to the MCU. Logic high VOH >= VCC-0.4 V at IRXD = -1.5 mA; logic low VOL <= 0.4 V at IRXD = 1.5 mA. Maximum output current 10 mA. |+| 2 | TXD | input | CAN transmit data input from the MCU. Logic high VIH >= 0.7*VCC, logic low VIL <= 0.3*VCC. Internal ~10 kΩ pull-up to VCC; drive strength IT >= 2 mA. Dominant timeout tto(dom)TXD = 0.3 to 3.8 ms. |+| 3 | GND | power_in | Input-side power ground, referenced to the MCU/logic domain. Isolated from CANG by 2500 VDC. |+| 4 | VCC | power_in | Input-side power supply, +5 V nominal (4.75 to 5.25 VDC). Quiescent current ~9 mA typical, max operating current 90 mA. |+| 5 | CANG | power_out | Isolated output-side ground reference for the CAN bus. Typically left floating in simple applications; connected via shield/GDT/earth in surge-protected designs. |+| 6 | CANL | bidirectional | CAN bus low signal (ISO 11898-2 compliant). Dominant V(OD)CANL ~1.5 V, recessive ~2.5 V (no load). Bus pin max withstand -40 to +40 V; leakage +/-5 uA at VCC=0. |+| 7 | CANH | bidirectional | CAN bus high signal (ISO 11898-2 compliant). Dominant V(OD)CANH ~3.5 V, recessive ~2.5 V (no load). Differential dominant Vdiff(d) ~2 V into 60 Ω. Bus pin max withstand -40 to +40 V. |++## 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.++- `CTM1051MG`+- `CTM1051AMG`++## CAD (KiCad official)++- Symbol: `CTM1051MG`+- 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/8588947688716558336) (6 pp, sha256 `cc48129ccb226cd8`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
