Temperature Control

A sensor in the tip lets the station hold a set temperature as you touch a pad. Without it, the tip sags on a header’s ground pin and overheats tiny pads.

Thermal Recovery

ESP32 board ground pins connect to big copper planes. A good iron recovers heat in a second, so each joint flows instead of going grainy.

Cheap, Common Tips

Tips wear out. Hakko T18, Weller ET and TS-series tips are easy to find, so you can keep a chisel for headers and a fine conical tip for SMD.

Station or USB-C?

Stations live on the bench and recover heat best. USB-C irons are tiny, heat in seconds and travel anywhere, but need a 65 W+ PD charger.

ESD Safety and Sleep

A grounded, ESD-safe tip protects 3.3 V parts, and an auto-sleep timer saves the tip and your bench when you walk away.

The WE1010NA is the station you’ll see in school labs and repair benches, and it’s an equally good choice for a serious ESP32 bench. The 70 W WEP70 iron is slim and comfortable, tips change by hand without tools, and standby with auto-setback drops the temperature when the iron sits in its rest, which extends tip life a lot if you solder in short bursts between flashing firmware. The whole chain is ESD safe, and a password lock keeps settings fixed on a shared bench. Weller’s ET tips cost a little more than Hakko’s, and it’s priced at the top of this guide.

The TS101 is Miniware’s refined take on the smart iron and a step up in polish from the Pinecil. It runs from USB-C PD or a DC barrel jack, reaches 65 W, and has a crisp OLED showing tip temperature and supply voltage, which is useful for confirming your charger is actually negotiating 20 V. The aluminium body feels solid, the firmware lets you tune sleep timers and motion wake, and it uses the same TS-series tips as the TS100 and Pinecil. Like every USB-C iron, it needs a proper PD charger to perform. Pick it over the Pinecil if you want better build quality and a nicer screen.

If you’re setting up an ESP32 bench from nothing, the X-Tronic 3020-XTS puts almost everything in one box: a 75 W digital station with an LED readout and °C/°F switch, a 10-minute sleep function, two helping hands to hold a board while you solder headers, a roll of solder, and a brass tip cleaner with flux. It isn’t as refined as a Hakko and its tips wear faster, but the temperature control is genuine, and the accessories are exactly what a first-time builder needs. It’s a much better first station than a no-name pencil iron.

The YIHUA 939D+ is the least expensive station we’d trust with an ESP32 board. You get a digital display, real temperature regulation, three memory presets (we’d set them to about 300, 330 and 370 °C), a sleep mode and a detachable iron, with spare tips and a little solder included. Recovery on big ground pads is slower than a Hakko’s and the tips are average, but for headers, jumper wires and through-hole sensors it does the job well for a fraction of the price.

The WLC100 has been a first soldering station for a generation of makers. It’s an analog unit: the dial sets power from 5 to 40 W rather than a precise temperature, so you learn to judge it by how quickly solder melts. That makes it slower and less precise than the digital stations above, but it’s simple, durable and comfortable, with Weller build quality and a built-in stand. It’s fine for headers and wires on ESP32 boards; skip it if you plan to do fine SMD work.

If you only need to solder the headers on your first ESP32 board and aren’t sure you’ll do more, the Plusivo kit is a low-risk start. The 60 W iron has a temperature dial, and the kit adds a stand, a desoldering pump, tweezers, solder, spare tips and a practice PCB to get the technique right before touching a real board. The dial isn’t closed-loop, so it can’t hold temperature like the stations above, and you’ll likely outgrow it. Start low on the dial and turn up only until solder flows.

9. FNIRSI HS-02A 100 W USB-C Smart Iron

A newer rival to the Pinecil with a 100 W ceiling over USB-C PD, a small colour IPS screen, three temperature presets and auto-sleep, and this kit includes six tips. It heats very quickly and has the extra power for thick wires and battery tabs. Note that it needs a 100 W PD charger to reach full power, and HS-02A tips don’t fit the precision HS-02B model, so buy tips to match.

10. YIHUA 926 III 60 W Station Kit

A space-saving station that combines the control unit and iron holder in one small box, with PID temperature control from 90 to 480 °C, sleep and calibration functions, and a generous kit: two helping hands, six tips, lead-free solder, a solder sucker and tweezers. It’s a strong alternative to the X-Tronic kit if your desk is small.

One iron for years

The Hakko FX888D, or the Weller WE1010NA if you want standby and a sleeker iron.

Small desk or travel

The Pinecil V2 or TS101 with a 65 W+ USB-C PD charger.

Everything in one box

The X-Tronic 3020-XTS or the compact YIHUA 926 III kit.

Tight budget

The YIHUA 939D+ for real temperature control at the lowest price.

First time soldering

The Plusivo kit to learn, or the Weller WLC100 for a trusted brand.

Thick wires and battery packs

The FNIRSI HS-02A on a 100 W charger, or a station with a large chisel tip.

Do I need a soldering iron to use an ESP32?

Not always. Many DevKit boards come with headers already fitted and work straight on a breadboard. You’ll need an iron when a board ships with loose headers, when you use castellated boards like the XIAO, or when you move a working circuit onto perfboard. Our ESP32 starter kits guide lists kits that need no soldering.

Can I damage my ESP32 by soldering it?

Rarely, if you use a temperature-controlled iron around 330 °C and keep each joint to a few seconds. Damage usually comes from an uncontrolled iron that runs far too hot, from lifting pads by pressing hard, or from solder bridges between neighbouring pins. Check every joint with a magnifier and a multimeter before powering the board.

Leaded or lead-free solder for ESP32 projects?

For hobby work, 63/37 leaded rosin-core solder in 0.6–0.8 mm is the easiest to use: it melts lower and flows cleanly. Lead-free needs about 30–40 °C more and more flux. With either, work in a ventilated space or use a fume extractor, and wash your hands afterwards.

What charger do I need for a USB-C soldering iron?

A USB-C Power Delivery charger that offers 20 V at 3 A or more (65 W+), plus a cable rated for it. Many laptop chargers qualify. A phone charger won’t supply 20 V, so the iron will run at a fraction of its power and struggle on ground pins.

What else do I need besides the iron?

Solder, flux, a brass tip cleaner, a pair of flush cutters and something to hold the board. For the rest of your bench, see our prototyping supplies guide and our programmers and debugging tools guide.
