Pros & Cons
MINIWARE TS101 Smart Cordless Soldering Iron
Pros
- OLED display and USB-C power adapter — genuinely programmable temperature control in a pen-sized iron
- 65W adapter gives real heat recovery for a cordless-format iron, closer to a small bench station than a battery pencil
- Adjustable 50–400°C range covers most hobbyist and light-repair soldering
- Fills the 'compact smart iron' niche that buyers researching Pinecil-style irons are actually looking for
Cons
- Not the Pine64 Pinecil specifically — MINIWARE is a separate, established brand in the same smart-iron category; verify which ecosystem's tips/firmware you want before buying
- 65W ceiling means it's still behind a full-size mains station on large thermal-mass joints
- Programmable features have a learning curve compared to a simple digital-display station
- Amazon stock has run scarce — confirm availability before ordering
Uni-T UT139C True-RMS Multimeter
Pros
- True-RMS measurement — essential for AC signals beyond simple sine waves
- Auto-ranging saves constant dial adjustment during debugging sessions
- NCV (non-contact voltage) tester built in
- CAT III 600V safety rating — appropriate for bench and household circuits
- Backlit display readable in dimly lit workbenches
- Remarkably accurate for the price: <1% DC voltage deviation in testing
Cons
- Capacitance measurement is slow compared to dedicated component testers
- Lead quality is mediocre — upgrade to silicone-insulated leads for regular use
- No data logging or USB output
- Case feels plasticky — survivable but not drop-proof
