PINE64 PINECIL smart mini soldering iron – Portable USB-C PD + DC input, OLED temperature control (100–400°C)

The PINECIL is a compact, smart portable soldering iron that reaches working temperature in about 12 seconds and offers precise temperature control from 100°C to 400°C via an OLED-driven interface.

Built around a 32-bit RISC-V SoC and running Ralim’s IronOS, the PINECIL blends full-featured controls with a slim, pocketable chassis. It accepts dual power inputs (USB-C PD/QC and a DC5525 barrel jack), includes an easy-to-read white OLED display, and features auto-standby to conserve power and improve safety. The unit ships with a Type B2 tip and is suitable for hobbyists, technicians, and makers who need a fast, accurate iron for fieldwork or bench tasks.

How quickly does the PINECIL get ready for soldering?

The PINECIL is designed for rapid warm-up so you spend less time waiting and more time working. From cold it reaches typical operating temperature in roughly 12 seconds and supports an on-demand rapid boost for brief higher-power heating.

• Typical warm-up: ~12 seconds to operating range
• Rapid boost mode for quick extra heat when needed
• Temperature range: 100°C–400°C for wide material compatibility
• OLED shows target and actual temperatures for fast verification

What power options are available for portable use?

You can run the PINECIL from a USB-C PD/QC 3.0 source or from a DC5525 barrel jack, giving flexibility in the field or at the bench. Note that power supplies are not included, so choose a compatible PD power bank or DC adapter rated for the required voltages and currents.

• USB-C: PD and QC 3.0 compatible — supports modern power banks and chargers
• Barrel jack: DC5525 input when you have a dedicated 12–21V adapter
• Current capability up to 3A depending on source and voltage
• Designed to work with standard accessories for mobile setups

How precise and usable is the PINECIL’s temperature control?

Temperature is set and monitored with the OLED display and adjustment buttons, delivering repeatable settings for delicate electronics or heavier lead-free solder jobs. IronOS provides responsive control and the display makes it simple to confirm the set point and actual tip temperature.

• Adjustable range: 100°C to 400°C for low- and high-temp tasks
• 0.69" white OLED shows real-time temperature and settings
• Buttons allow quick increments and fine adjustments on the fly
• Auto standby reduces tip wear and saves power during idle periods

What materials and package details affect portability and durability?

The PINECIL combines a stainless steel core with a polycarbonate shell to balance heat resilience and lightness. Its compact footprint and 88 g weight make it easy to carry in a tool roll or small bag, while included tip compatibility and compact packaging keeps a basic setup minimal.

• Construction: SAE 304 stainless steel core with polycarbonate housing
• Weight: 88 grams — designed for handheld and travel use
• Package dimensions: 17 × 12 × 2.3 cm for compact storage
• Included: PINECIL soldering iron and Type B2 soldering tip

Who is this for? The PINECIL suits electronics hobbyists, repair technicians, makers, and students who need a fast-heating, accurate soldering tool they can take anywhere. It’s particularly useful for field repairs, rapid prototyping, small board assembly, and anyone who values small form factor tools with modern power options and clear temperature control.
