Get soldering quickly at the bench or out in the field with this compact smart soldering iron. It reaches operating temperature in just six seconds and provides digital temperature control from 100°C to 400°C, making it suitable for delicate SMD work through to heavier wire splicing.
The iron can be powered from a high-wattage USB-C supply with PD or QC 3.0 support, or from a DC5525 barrel jack connected to a suitable DC source. An OLED display and integrated adjustment buttons make it easy to set and monitor the temperature.
PINECIL comes pre-loaded with Ralim's open-source IronOS firmware for customisation and community-driven features. The included B2 soldering tip installs quickly, and the lightweight plastic body includes a metal clip for easy handling.
Features:
- Fast heat-up: Reaches operating temperature in just six seconds.
- Digital temperature control: Adjustable from 100°C to 400°C.
- OLED display: Easy-to-read display for setting and monitoring temperature.
- Integrated adjustment buttons: Dial in the heat you need directly on the iron.
- Dual Power Options: Power the iron using either a high-wattage USB-C cable (PD and QC 3.0 supported) or a standard DC5525 barrel jack.
- Auto Standby: A built-in IMU detects motion, automatically dropping the temperature into sleep mode when you set it down to prevent burns and preserve the tip.
- Open-source firmware: Pre-loaded with Ralim's IronOS.
- Included tip: B2 soldering tip installs quickly.
- Portable body: Lightweight plastic body with a metal clip for easy handling.

Useful for electronics repair, maker projects, SMD soldering and general wiring tasks where a small, flexible soldering iron is preferred.
Jargon buster
Plain-language definitions for the technical terms used above.
- BL
- BL usually stands for backlight, the light source that makes an LCD visible. Some modules let you control this pin to turn the backlight on, dim it, or save power in battery projects.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- IMU
- An IMU (Inertial Measurement Unit) combines motion sensors, typically an accelerometer and gyroscope and sometimes a magnetometer, to measure movement and orientation. It can sense motion, tilt, vibration, rotation, and changes in direction, which is useful for tasks such as navigation, stabilisation, gesture detection, and asset tracking.
- OLED
- OLED stands for organic light-emitting diode, a display type where each pixel produces its own light. It matters because OLED screens are thin, high-contrast and easy to read for small status displays, but they can be more sensitive to image burn-in than some other display types.
- RISC-V
- RISC-V is an open, royalty-free processor instruction-set architecture used in chips ranging from tiny microcontrollers to Linux-capable application processors. The choice of RISC-V determines which compilers, software tools, and performance or low-power features are available, separate from the more common Arm or x86 architectures.
- SMD
- SMD means surface-mount device, a component style designed to be soldered directly onto the surface of a circuit board rather than through holes. SMD parts are compact and mounted flat on the board, which suits smaller and mass-produced designs.
- USB-C
- USB-C is a small, reversible USB connector that can carry power, data and, on some devices, video over a single cable. The same connector can range from charging only to high-speed data, so the functions a given port actually supports vary.
